Heat Transfer Modes Study

This apparatus allows the demonstration and study of the different modes of heat transfer: conduction, free or forced convection, and radiation. Educational Objectives: Influence of the inclination of a flat plate on heat transfer by natural or forced convection. Determination of the thermal conductivity of different materials. Learn about Heat Transfer Modes Study specifications for optimal educational outcomes.. Study of the chimney effect under free or forced convection. Study of radiation from a 'black' plate and a 'grey' plate and determination of the emissivity factor of the latter surface. Learn about Digital Heat Transfer Modes Study for optimal educational outcomes..

The apparatus is based on the use of a flexible heating plate with low thermal inertia, temperature-regulated. Measuring the heating power required to maintain this plate at a chosen setpoint temperature allows determination of the various heat exchanges.

Two flexible heating plates with low thermal inertia, temperature-regulated: one with a matt black face and a shiny face, the other uncoated. Heating power approximately 50 W A set of plates of different insulating materials for conduction study An adjustable support on which the heating plates and material plates are placed A tubular conduit in insulating material for chimney effect study A fan for forced convection demonstration An electronic control box comprising: an on/off regulator, two counters with reset for determining heating power, a voltmeter, an ammeter, a digital thermometer with a platinum probe for measuring surface or ambient temperature A chassis supporting the electronic control box and plate support A technical bulletin
