 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Diffusion Jet Flame Models Using Open Source Code CFD Software) ผู้เขียน:นายชาคริต สุวรรณจำรัส, อาจารย์ , Panya Aroonjarattham สื่อสิ่งพิมพ์:pdf AbstractOpen-source code software (OpenFOAM) based on computational fluid dynamics (CFD) was implemented and applied to simulate the diffusion of a jet flame. The large eddy simulation (LES) of the turbulence combustion model was written using the C++ language. The mixture fraction approach, an infinitely-fast chemistry assumption and radiative heat transfer were combined with this LES model. The finite volume method was performed to solve and simulate diffusion jet flame models under varying methane flow rates and environmental pressures. The results of the jet flame simulation comprising the percentage of maximum burning temperature, the heat release rate and oxygen from the oxygen fraction were defined to be the flame shape for validation with experiments. It was found that the flame length measured using the heat release rate from the results of simulations had the best agreement with the experiments. An average error of less than 5.84% was obtained by a comparison between the developed CFD model and the experiment when the CFD flame length was depicted by the heat release rate. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Simulation of Three Dimensional Liquid-Sloshing Models using C++ Open Source Code CFD Software) ผู้เขียน:เอกชัย ชัยชนะศิริ, นายชาคริต สุวรรณจำรัส, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe open source computational fl uid dynamic (CFD) codes—open fi eld operation and manipulation (OpenFOAM)—were developed to simulate the three dimensional sloshing of liquid inside moving rectangular tanks. Equations governing the two-phases of fl uid were used in these simulations and the Volume of Fluid method was used to capture the free surface of the liquid sloshing. The fi nite volume method was used to solve these problems. The solutions of the simulations were validated using experiment results based on the free surface height and the pressure developed on the wall of the tanks. It was found that the average error of the surface height and the pressure obtained from the simulations were 2.33% and 6.65%, respectively. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Implementation and Validation of k-? Turbulence Model using C++ Open Source Code Software for Thermal Dispersion in Domestic Water Heater) ผู้เขียน:Wisuwat Matchika, นายชาคริต สุวรรณจำรัส, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe governing equations of the k-? turbulence model were implemented using open source computational fluid dynamic (CFD) codes and open field operation and manipulation (OpenFOAM) software to simulate the thermal dispersion between the water flow and the heater in a domestic water heater. The C++ language was used to develop the CFD codes. The QUICK (Quadratic Upstream Interpolation for Convection Kinetics) scheme was applied with the k-? turbulence model of the thermal dispersion and fluid flow. The SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) algorithm was used to solve the pressure-velocity coupling under turbulence flow. The solutions of the simulations were validated using the experimental results. The transient temperatures at the outlet port of the domestic water heater were obtained using a data acquisition (DAQ) device via K-type thermocouple lines. Twelve cases of the CFD were performed in this study and produced an average error of less than 2.13% when the CFD temperatures were compared with the experimental temperatures. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The k-? Turbulence Model to Simulate the Two-Phase Flows of Fluids in Flumes using C++ Open Source Code Computational Fluid Dynamic Software) ผู้เขียน:เอกชัย ชัยชนะศิริ, นายชาคริต สุวรรณจำรัส, อาจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe governing equations of two-phase flows based on the k-? turbulence model were developed using open source computational fluid dynamic codes and open field operation and manipulation (OpenFOAM) software to simulate water flows in a flume. The water surface was modeled using the volume of fluid method with a turbulence model. The PISO (pressure implicit with splitting of operator) algorithm was used to solve the pressure-velocity coupling in the two-phase flows. The solutions of the simulations were validated using the experimental results as free surface profiles on the wall of the laboratory flume in transient and steady time periods. The transient time period started from when the water was distributed into the flume until it began to overflow the top of the weirs. The steady time period accounted for the water overflowing the weirs and the surface profiles did not change. It was found that the average error of the surface profiles in the transient and steady time periods obtained from the simulations was 8.94% and 8.06%, respectively. |
