TH 320 FREE AND FORCED CONVECTION
The unit is used for studying heat transfer by free and forced convection in a vertical duct.
A heating surface is attached to the middle of the duct. Three types of heating surfaces are available i.e. vertical flat plate, plate with cylinders, and finned plate. A front window is provided for visual observation of the heating surface. Air enters the duct at the bottom duct with flow straightener and escapes via the top. A fan is attached to the top of the duct to induce forced convection. Air velocity is measured by a thermal probe anemometer. Temperatures of hot surface and of air at different points in the duct are measured by thermocouples.
A service module provides power supply, heater control unit, and measuring instruments.
Instruction manual is also included.
