Heat Transfer in Natural Convection
Heat transfer through natural convection: Apparatus for Measuring Heat Transfer Coefficient through natural convection
The setup is designed and fabricated to study natural convection phenomenon from a vertical cylinder in terms of average heat transfer coefficient.
The apparatus consists of a brass tube fitted in rectangular duct in vertical fashion. The duct is open at top and bottom and forms and encloses which serves the purpose of undisturbed surrounding. One side of it is made of glass/acrylic for visualization. A heating element is kept in a vertical tube which heats the tube surface.
The heat is lost from tube to surroundings by natural convection. The temperature is measured by seven temperature sensors. The heat input to the heater is measured by digital ammeter and digital voltmeter and can be varied by dimmer stat.
