Numerical Study of Natural Convection in a Rectangular Enclosure with Cooling Strip

냉각부(冷却部)를 갖는 사각형(四角形) 밀폐공간내(密閉空間內)의 자연대류(自然對流)에 관(關)한 수치해석(數値解析)

The influence on natural convection was studied by solving the partial differential equations within a rectangular enclosure which have a cooling strip at the right side wall of the space, a isothermally heated bottom plate and adiabatic two other walls. Computation was carried out for the range of Grashof number from $5*10^3$ to $2.5*10^5$ with Plandtl number of 0.73. The results have been obtained in cases of four aspect ratios and various strip sizes. Temperature and Stream function distributions have been plotted using explicit finite difference method in two dimensional, laminar flow, and also mean Nusselt number and Local Nusselt number have been obtained.
