Numerical analysis of phase change inside horizontal pipe with consideration of density inversion effect of water

물의 밀도 역전 현상을 고려한 수평 배관내의 자연대루 및 상변화 현상의 수치적 해석

This paper deals with the numerical analysis of natural convection flow induced by the density inversion effect of water inside horizontal pipe. The numerical method is based on SIMPLE/PWIM in general coordinate for its wide applicabilities. The numerical tool was validated through the comparison with the previous results concerning the density inversion effect of water It is shown that the developed numerical tool could predict the flow pattern and the heat transfer phenomena qualitatively And it is also found that the density inversion effect of water has significant effects on the flow pattern.
