The project emphasis on the performance of pin-fin based heat transfer analysis and it also describes the fabrication of pin-fin and venturimeter. The project involves use of venturimeter for measuring flow rate, centrifugal blower, thermostats and variac. The blower acts as source for forced convection, pin-fin is heated by an electrical heater. Thermocouples are mounted along the length of the fin for temperature measurement and the duct at the exit. Here at the exit a venturimeter is provided for flow rate measurement. By this experiment the efficiency and heat transfer coeffiecient of a pin-fin in forced convection is investigated.
