The natural convection in a three dimensional enclosure using color capturing technique and computation
색상 포착 기법과 수치계산을 이용한 3차원 밀폐 공간내의 자연대류 연구
- Published : 1997.12.01
The natural convection of a horizontal layer heated from below in a three-dimensional rectangular enclosure was dealt with both numerically and experimentally. The aspect ratios are 1:2:3.5 and Boussinesq fluid is water with the Prandtl number of 5.0. This experimental study showed how to measure the variation of temperature field in a 3-D rectangular enclosure with small aspect ratios by using TLC(Thermochromic Liquid Crystal) and color capturing technique. The experimental temperature field had periodic characteristics of 75 sec at Ra=2.37*10
