부채형 공간내의 자연대류에 관한 수치해석적 연구
A Numerical Study of Natural Convection within a Trapezoidal Enclosure
초록
The natural convection heat transfer within a trapezoidal enclosure with parallel cylindrical top and bottom walls at different temperatures and two adiabatic side walls are studied. A finite-difference method has been used to solve the governing equations numerically. The range of parameters studied herein are Prandtl number 0.7, aspect ratio from 0.5 to 4.0, Rayleigh number from
