Figure 4. CFD simulation results for Models A (panels A and C) and B (panels B and D) in steady 5.6 m/s flow. The blue, yellow, and green regions are areas of reduced flow speed that generate forces on the tags. The upper panels show the flow speed over a horizontal cross-section at the tag midline. The lower panels show flow speed over a vertical cross-section at the centerline of the tag. The improved flow around Model B is evident in the smaller magnitude of blue coloration in the wake behind the tag.
KMC Models and CFD Simulations for Catalytic CO Oxidation over RuO2
<p>The large tar.gz file (~15GB) has the CFD Data Set for CFD Simulations for Catalytic CO Oxidation over RuO2 associated with the publication: doi: 10.1021/acscatal.8b00713 , https://pubs.acs.org/doi/abs/10.1021/acscatal.8b00713</p> <p>The smaller zip file(s) have the KMC model creation files, which are actually from this publication: https://doi.org/10.1088/1361-648X/aacb6d https://iopscience.iop.org/article/10.1088/1361-648X/aacb6d</p> <p>For the 110 KMC file, it must be compiled using the lat_int backend of kmos. The xml file generated takes less than an hour, though the exporting (compiling) may take 5 to 10 hours. With lateral interactions, the 110 xml file is >25MB. Without lateral interactions, the xml file is very small ( << 1 MB). Setting the "upToDistance" to 0 for each reaction in the python file called CO_O_RuO2_110.py will create a 110 model without lateral interactions (currently the "upToDistance" is set at 1 for each reaction, and thus includes nearest neighbor interactions). How to compile the model requires reading the documentation for the KMC software. The final syntax is " kmos export -b lat_int CO_O_RuO2_110.xml "</p> <p>For the 111 KMC file, it should be compiled with the default ( local_smart ) backend of kmos. The lateral interactions are already included and cannot be easily turned off. The resulting files are small. How to compile the model requires reading the documentation for the KMC software. The final syntax is " kmos export -b local_smart CO_O_RuO2_111.xml "</p> <p>Primitive example KMC runfiles are included, which would need to be run in the compiled KMC model's directories, though current conventions of kmos simulations use more advanced runfiles.</p> <p> </p>

Data from: Study on the optimization of the deposition rate of planetary GaN-MOCVD films based on CFD simulation and the corresponding surface model
Metal-organic chemical vapour deposition (MOCVD) is a key technique for fabricating GaN thin film structures for light-emitting and semiconductor laser diodes. Film uniformity is an important index to measure equipment performance and chip processes. This paper introduces a method to improve the quality of thin films by optimizing the rotation speed of different substrates of a model consisting of a planetary with seven 6-inch wafers for the planetary GaN-MOCVD. A numerical solution to the transient state at low pressure is obtained using computational fluid dynamics. To evaluate the role of the different zone speeds on the growth uniformity, single factor analysis is introduced. The results show that the growth rate and uniformity are strongly related to the rotational speed. Next, a response surface model was constructed by using the variables and the corresponding simulation results. The optimized combination of the matching of different speeds is also proposed as a useful reference for applications in industry, obtained by a response surface model and genetic algorithm with a balance between the growth rate and the growth uniformity. This method can save time, and the optimization can obtain the most uniform and highest thin film quality.

The influence of flow electrode channel design on flow capacitive deionization performance: Experimental and CFD modelling insights
<p>Flow capacitive deionization (FCDI) is an emerging desalination technology at which flow electrodes (shearthinning<br>flowable carbon slurries) are used to remove ions from saline water. The geometry of flow electrode<br>channels, which provide the path and ensure the distribution and mixing of the flow electrodes, is one of the most<br>important aspects to be optimized. This work presents experimental and computational fluid dynamics (CFD)<br>modelling analysis of the influence of the geometry of flow electrode channels on FCDI performance. Flow<br>electrode gaskets (with open, serpentine (short) horizontal and serpentine (long) vertical channels) were 3D<br>printed using a polyethylene terephthalate glycol (PET-G) filament. The FCDI cell with a vertical serpentine flow<br>electrode channel exhibited the poorest performance due to channel blockage by carbon particles, while the best<br>results were achieved with a horizontal serpentine flow electrode channel. CFD simulations aided in understanding<br>this behaviour by showing that the channel geometry strongly affects the local shear rate, and thus the<br>local viscosity of flow electrodes. Thus, it is recommended to design channels that induce flow disturbance<br>aiming for increasing the shear rate and hence reducing flow electrode viscosity, therefore promoting their<br>flowability and reducing clogging chances.</p>

Modeling the nutritional value of thermally processed food products based on CFD simulations - Results of the Miniatura 6 NCN grant
<p>1. Description of the purpose of the scientific activity: The aim of the scientific activity was to optimize the heat treatment process of food products using Computational Fluid Dynamics (CFD) simulations and to assess the impact of this process on the nutritional value of the finished product. The following beef meat was selected for the study: strip beef, shin, entrecote, neck, leg, topside, topside, shoulder and brisket. The obtained results on the selection of heat treatment parameters, i.e. temperature, time, forced convection, allowed for the creation of a knowledge base on the basis of which a multi-factor optimization was carried out between the basic composition (the amount of: protein, fat, water, connective tissue and ash) and the content of conjugated linoleic acid (CLA) and vitamin E in beef. The aim and scope of the research has been achieved.</p> <p>2. Description of the implementation of the scientific activity: Experimental research was carried out at the Department of Food Technology and Design at the Warsaw University of Life Sciences. The raw material for the tests, i.e. beef meat from elements of different basic composition (protein, fat, connective tissue, ash, water): strip beef, rind entrecote, neck, leg, topside, topside, shoulder, brisket was purchased in three batches . The scope of the scientific activity included three stages:</p> <ul> <li>CFD simulation - computer simulation of heat treatment of beef characterized by a diverse basic composition and determination of the reduction of CLA and vitamin E content in various conditions of the thermal process - building a knowledge base,</li> <li>RSM optimization - using the CFD database of changes in the content of CLA and vitamin E, depending on the parameters of the thermal process, for optimization using the response surface method (RSM) - it allowed the selection of the best thermal treatment parameters ensuring the smallest losses of the above-mentioned bioactive ingredients,</li> <li>verification - laboratory tests were carried out using chromatographic techniques of vitamin E (HPLC - high-performance liquid chromatography) and CLA (GC - gas chromatography) content to confirm the predicted RSM results based on CFD simulation. Information on the mechanism of shaping the content of CLA and vitamin E in heat-treated beef allowed for the creation of a database that makes it possible to determine the optimal conditions for heat treatment of food products. The research was experimental, and the obtained results provided information on the mechanism of thermal decomposition depending on the parameters of the heat treatment process and the basic composition of food products. The scientific activity was used to develop a mechanism describing the relationship between the basic composition, method and parameters of heat treatment and the thermal stability of CLA and vitamin E in beef.</li> </ul> <p>3. Description of the effects of the implementation of the scientific activity:</p> <p>The study showed a significant effect of the basic composition of beef on changes in the content of vitamin E and CLA during heat treatment. The use of an innovative method of modeling and simulation of thermal processes with the use of CFD allowed for a precise analysis of changes in the content of the above-mentioned substances. components in meat samples of different basic composition. The analyzes carried out showed that the content of: protein, fat, tk. total, ash, water in individual elements of the beef carcass, i.e. strip beef, rib eye shank, neck, round, topside, topside, shoulder, brisket affects the temperature distribution in the entire volume of the raw material, which results in partial decomposition of vitamin E and CLA. Based on the developed experimental model, optimization was performed using the response surface method (RSM), thanks to which the best parameters of the heat treatment process using a convection steam oven were obtained. The optimization was carried out individually for each element differing in basic composition, and among the optimized process parameters were: processing temperature [℃], humidity inside the furnace chamber [%], process time [s] and fan speed ensuring forced convection of air and steam [RPM ]. The last, third stage of the research task was the verification of the optimization model with the results of laboratory analyses. The tests carried out using gas chromatography (GC) and high-performance liquid chromatography (HPLC) allowed to obtain the results of vitamin E and CLA content at a level consistent with those predicted on the basis of RSM models.</p>
