Heat Transfer in Forced Convection

Category:

The present set-up is designed to study the heat transfer in forced convection. It consists of a test pipe surrounded by a heater externally and fitted with a blower unit with valve for varying the air flow rate. Four Temperature Sensors are embedded on the test section and two are placed in the air stream at the entrance and exit of the test section. A digital temperature indicator measures the temperature profile along the test section. An orifice with manometer is fitted on the delivery side of the blower to measure the flow of air. A Digital Temperature Controller is provided to have an automatic smooth control on required heat input to the heater as per user requirements. Further steady state of experiment is achieved in very less time as compared to manual control. Electronic energy meter is provided to measure the heat input.
