An Experimental Study on the Natural Convection from the Isothermal Square Beam with an Adiabatic Wall

단열벽(斷熱壁)에 부착(附着)된 등온사각(等溫四角)비임에서의 자연대류(自然對流) 열전달(熱傳達)

Steady laminar natural convection heat transfer from an isothermal square beam with adiabatic wall has been studied for various inclination angles of the wall and Rayleigh numbers by using Mach-Zehnder Interferometer in air. The different temperature and fluid fields were obtained as the inclination angle changes showing the effects of the ascending heated fluid and the adiabatic wall. The maximum total mean Nusselt number was found at ${\theta}=45^{\circ}$.
