 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. |
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. |
