Numerical Study of Thermal Convection in Horizontal Enclosure with Heat Generating Conducting Body
발열 전도체를 가지는 밀폐계 내부의 자연대류 현상에 대한 수치적 연구
Abstract
The physical model considered here is a horizontal layer of fluid heated below and cold above with heat-generating conducting body placed at the center of the layer. The dimensionless thermal conductivities of body considered in the present study are 0.01, 1 and 150. The dimensionless temperature difference ratios considered are 0.25, 2.5 and 25. Two-dimensional solution for unsteady natural convection is obtained using an accurate and efficient Chebyshev spectral methodology for variety of Rayleigh number from
