Experimental study of turbulent thermal convection between two flat plates
실험적 방법에 의한 두 평판 사이의 난류 열대류의 해석

Abstract
Experiments have been conducted to investigate mean thermal structure in unstable turbulent thermal convection between two horizontal flat plates. The upper plate was kept at a constant cold temperature and the bottom plate at a constant hot temperature. Both air and water were used as its working fluids. Chamber aspect ratios were 3.80 and 6.17, the mean temperature differences between two plates were 2.6-9.3.deg. C, whose Rayleigh numbers in a range 6.13*10
본 연구에서는 논란의 여지가 많은 문제점을 구간별 특성 척도 분석으로 보다 명확히 하고, 매질이 물과 공기인 경우 실험을 통하여 난류 열대류 구조를 분석하여 척도분석 및 Kraichnan등의 분석을 통해 확인된 바 있는 지수법칙층의 존재를 확인하 고자 한다.
