Heat Transfer Through Composite Wall
Product Code : JA-HTLE-7370
The Heat Transfer Through Composite Wall apparatus (SKU JA-HTLE-7370) shows how heat is conducted through a wall made of several materials in series. A heater sits between stacked slabs of mild steel, bakelite and wood, clamped in a frame, and thermocouples record the temperature at each interface. This composite wall apparatus is used to find the total thermal resistance and the conductivity of each layer in mechanical engineering heat transfer labs.
Specifications
The composite wall apparatus is specified by its test slabs (MS, bakelite and wood, 2 of each), heater assembly, clamp plates and a control panel with a 12-channel digital temperature indicator, 0-3 A ammeter, 0-250 V voltmeter and 0-2 A dimmerstat. Slab sizes are confirmed on the quotation.

Experiments with the composite wall apparatus
The apparatus is used to show that the thermal resistances of layers in series add up, and to find the conductivity of each layer from the measured temperature drops at several heat inputs.
- Determining the total thermal resistance of a composite wall
- Finding the thermal conductivity of the composite structure
- Plotting the temperature gradient across the layers
- Plotting heat flux against thermal conductivity
