Analysis of Combined Convective Heat Transfer in Inverted T Shape Channel under Buoyancy ?Assisting Flows Using Dimpled Pin Fin

Vidya G. Kalebag | R. A. Kathar ^[2]

Abstract: Horizontal rectangular fin arrays are used for cooling of electronics components in the form of heat sink, in many situation a fan is mounted to increase the heat dissipation rate and thus there exist a problem of combined convection of horizontal rectangular fin array with this idea in mind the experiment setup was developed to work in the region of combined convection. The present paper also gives the effect of various velocities and power input on coefficients of heat transfer for combined convention using Al and Brass materials. The parameters considered are Reynolds number, Prandtl number, Nusselt number, heat transfer coefficient and heat transfer rate at various temperature difference. Two materials will be used i. e. Brass and Aluminium and parameter obtained will be compared for these two materials. With this limited objective the present work can be viewed as a starting step for carrying out for further research. The brass fins will be interest as a topic of research, however this requires very careful observation and adequate control on the parameter.
