공개 소스코드를 이용한 진동형 히트파이프에 대한 수치해석

다국어 초록 (Multilingual Abstract)

The phase change and the thermal fluid flow were simulated in a pulsating heat pipe using OpenFOAM source code. The interPhaseChangeFoam was chosen as a solver, which could compute the phase change of water and vapor. The mass transfer parameters were used to keep the mass balance of the evaporation and the condensation in the phase change process. The pressure equation was modified and the temperature equation was added in the interPhaseChangeFoam to circulate the working fluids. The volume fractions of water and vapor were visualized in the pulsating heat pipe. In order to verify the results of the numerical analysis, the thermal resistances of the pulsating heat pipe were calculated with input power and compared with the previous research data. As a result, the thermal resistances decreased with input power and the trend was similar to that of the previous results.
