Abstract

The objective of this experimental work is to study the effect of the shutter geometry on the free convection flow of ward air through the window. For this purpose, a setup is fabricated to measure the temperature variations on both sides of a test section, which is similar to a real shutter under different geometrical conditions. The space of one side is heated by a hot plate, while the other is kept unheated. The effect of the shutter angle and aspect ratio on the temperature distribution on both sides has been examined. Ideal shutter is the one which acts as a thermal diode, by allowing the free convection flow of warm air only in one direction. The ability of the shutter to resist the free convection flow of warm air through the window in a certain direction. Increases by increasing the shutter angle and aspect ratio. Results which are given in graphical form, have shown that the shutter angle and aspect ratio should be more than 45 and 4 respectively, to obtain a good performance.
