ABSTRACT = {Inserting the jet plate between the bottom plate and absorber plate in a flat plate solar air heater has been proposed as an excellent option to enhance 
the performance of the conventional solar air heater. This research work presents an experimental study of flow and heat transfer in a jet plate solar air 
heater. Results are presented for the different mass flow rates of air <i>ṁ1</i> and <i>ṁ2</i>, Reynolds number <i>Rej<sub>a2</sub></i>, streamwise pitch of the holes to jet hole diameter 
<i>X/D</i>, depth of upper channel to jet hole diameter <i>Z<sub>2</sub>/D</i>, fixed number of jet hole <i>N</i> and angle of tilt <i>θ</i>. In the present study, it is found that outlet air 
temperature, collector efficiency, heat transfer coefficient and Nusselt number are higher at lower jet hole diameter, <i>D</i> (6 mm) as compared to higher 
jet hole diameter, <i>D</i> (8 mm and 10 mm) irrespective of the mass flow rates, <i>ṁ1</i> and <i>ṁ2</i>. The outlet air temperature decreases with increase of mass flow 
rates of air (<i>ṁ1</i> and <i>ṁ2</i>) and jet hole diameter. Based on the experimental data, the correlation for Nusselt number has been developed.},
