Heat Transfer From A Pin- Fin

HT 08
 
HEAT TRANSFER FROM A PIN FIN
 


 
The setup is designed to study the heat transfer in a pin fin. It consists of pin type fin fitted in duct. A fan is provided on one side of duct to conduct experiments under forced draft conditions. Airflow rates can be varied with the help of damper provided in the duct. A heater heats one end of fin and heat flows to another end. Heat input to the heater is given through Variac. Digital Temperature Indicator measures temperature distribution along the fin.
 

 

EXPERIMENTS
 


 

To study temperature distribution along the length of fin in both Free & forced convection
 
Comparison of theoretical temperature distribution with experimentally obtained distribution
 


 

UTILITIES REQUIRED
 


 

Electricity Supply: 1 Phase, 220 V AC, 5 Amp.
