DESCRIPTION:

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

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

EXPERIMENTATION:

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

UTILITIES REQUIRED:

• Electricity Supply: 1 Phase, 220 V AC, 5 Amp.
• Table for set-up support.
• Computer System: Pentium IV with DVD Drive, Windows 7, MS-Office pre-loaded. One USB slot
• required in PC for DATA ACQUISITION CARD.
