Abstract: Abstract— The current paper is a review of various types of inlet condition of air (00,450,900) and baffle arrangement. The utilization of baffles in channel is usually used for passive heat transfer enhancement strategy in single phase internal flow. Heat transfer improvement technology is that the method of rising the performance of a heat transfer by increasing the convective heat transfer coefficient. Typically, the main objective is to cut back the dimensions and prices of heat exchanger. General techniques for enhancing heat transfer is divided in two classes. One is Passive Methodology like twisted tapes, whorled screw tape inserts, rough surfaces, extended surfaces, baffles, additives for liquid and gases. The other class is Active methodology, which needs additional external power, for instance mechanical aids, surface fluid vibration, use of electricity fields. Passive heat transfer strategies have been found additional cheap as compared to active strategies. Baffle may be a standard heat transfer improvement device employed in numerous heat-exchanging channels. The flow blockages like baffles increase the pressure drop and ends up in augmented viscous impact owing to reduced fluid flow space. In most of the previous numerical and experimental studies empirical correlations for duct flow with straight channel has been investigated and corresponding heat transfer and pressure drop are reported, only a few paper are presented for channel with turned flow therefore an experimental study is required to be carried during a rectangular channel with turned flow (450,600, 900) varying the Reynolds number which indicates turbulence flow. The Reynold number is in range of 3000 to 28000 which indicates turbulence flow. The Rectangular channel would be heated from bottom with a uniform heat flux. A Independent heater arrangement would be made at the inlet to vary the inlet temperature. Considering the speedy rise in energy demand, most effective heat transfer enhancement techniques became important job worldwide. Theoretical and empirical correlations for duct flow are given for hydro dynamically and thermally developed flow in most of previous studies However the effect of baffle height and different inlet condition on heat transfer and pressure drop are going to be examined. Finally the comparison of the results of experimental investigation with the results obtained by using correlation method will be done
Keywords: Rectangular channel, Reynolds number, Turbulent, inlet angle, convective heat transfer coefficient, heat transfer enhancement, baffle height, uniform heat flux.
