Flow Control and Heat Transfer in a Squared Room Applying Thin Obstacles at Walls

This paper aims at simulating and selecting an appropriate simple air-conditioning system (inlet and outlet) for a square room based on the fluid mechanics and heat transfer characteristics. Three different outlets have been investigated at different corner of the room under constant inlet position for all three cases. It is shown than an appropriate selection of outlet can affects the results of the heat circulation, considerably. Later, a couple of rectangular arrangement obstacles have been proposed in the best case of the study in order to improve the mixing and heat transfer characteristics more considerably. The effect of the obstacles heights and the gap between the them on the flow control and mixing time are also investigated, showing that the position and the geometry of these obstacles can be very influential.
