Experimental study on the natural convection in an enclosure with an adiabatic body using the two-color LIF method

Two-color LIF 기법을 이용한 단열체가 있는 밀폐계 내에서의 자연대류에 관한 실험적 연구

Most of the previous studies on natural convection were based on the numerical analysis, and some experimental studies considered the classic case of thermal convection. In this study, an adiabatic square body was located at the center of an enclosure between the bottom hot and top cold walls. And the measurement of the detailed temperature fields was conducted by the method of two-color Laser Induced Fluorescence using a Nd:Yag laser. As a result, heat transfer characteristics of natural convection with an adiabatic body was estimated as a function of time over a range of Rayleigh numbers.
