Construction and Design

The Radial Heat Conduction Module ThermoFlux-7049/2 is constructed around a circular brass disc measuring 110 mm in diameter and 6 mm in thickness, mounted on a bench support frame. The disc is insulated to minimise external heat loss and ensure that conduction occurs primarily in the radial direction. An electric heater positioned at the centre of the disc provides the heat source, with power supply, control, and measurement handled by the Heat Transfer Service Unit ThermoFlux-7049. A copper tube is bonded to the outer edge of the disc and carries cooling water to maintain the periphery at a lower, consistent temperature, establishing the radial temperature gradient required for conduction experiments. Six thermocouple holes are drilled at equal radial increments between the centre and the edge, providing six discrete measurement points across the full radial span of this radial heat conduction module. Thermocouples inserted into these holes connect directly to the Heat Transfer Service Unit for real-time digital temperature display. The setup allows full investigation of steady-state radial conduction and transient unsteady-state behaviour, with all data required for Fourier Rate Equation calculations available from the six radial temperature readings and the measured heater power input.

Q1: What is the disc material and geometry used in the Radial Heat Conduction Module ThermoFlux-7049/2?
The disc is made of brass, 110 mm in diameter and 6 mm thick, with an electric heater at the centre and a copper cooling tube bonded to the periphery.

Q2: How many temperature measurement points are available on this radial heat conduction module?
Six thermocouple holes are positioned at equal radial increments from the heated centre to the cooled edge of the disc, providing a complete radial temperature profile.

Q3: Is the Heat Transfer Service Unit included with the ThermoFlux-7049/2?
No. The Heat Transfer Service Unit ThermoFlux-7049 is required for operation and must be ordered separately. It provides heater power control, power measurement, and digital temperature display.

Q4: What equation is used to determine thermal conductivity from the experimental data?
The Fourier Rate Equation is applied to the measured radial temperature distribution and heater power input to calculate the thermal conductivity (k) of the brass disc material.

Q5: Does the module support unsteady-state as well as steady-state conduction experiments?
Yes. The module supports both steady-state radial temperature distribution experiments and unsteady-state conduction analysis, including measurement of the time required to reach stable thermal conditions.
