The Radial Heat Conduction accessories have been designed todemonstrate the application of the Fourier rate equation to simple steady-stateconduction radially through the wall of a tube.
Hardware Description:
The accessory comprises a soliddisk of material, which is heated at the centre and cooled at the periphery tocreate a radial temperature difference with corresponding radial flow of heatby conduction.
Six K-type thermocouples arepositioned at different radii in the heated disk to indicate the temperaturegradient from the central heated core to the periphery of the disk.
The arrangement, using a solid metal disk with temperature measurementsat different radii and heat flow radially outward from the centre to theperiphery, enables the temperature distribution and flow of heat by radialconduction to be investigated.
The heater power and the cooling water flow rate are controlled via,either from the front panel or from the computer software. These are controlledmanually.
A control valve permits the flowof cooling water to be varied, if required, over the operating range of 0-1.5l/min.
The cooling water flow rate ismeasured by a turbine type flow sensor .
An optional cooling water flowrate sensor Set 2 is available upon request for the connecting directly intothe service unit.
The radial distance between eachthermocouple in the disk is 10mm.
Quick-release connectionsfacilitate rapid connection of the cooling tube to a cold water supply. Apressure regulator is incorporated to minimise the effect of fluctuations inthe supply pressure.

The Alternative Fueled Engine program includes a dynamometer, which is attached to an oil-less engine allowing the student to measure the engine's horsepower. Also, this patented electric dynamometer con-verts useful power to electrical energy. Alternative Fueled Engine patented oil-less, four stroke transparent engine can run on any alternative fuel. With the ability to vary timing or change the compression ratio, this trainer is the world's most unique teaching device. The ADVANCED LEVEL Program provides experiments in the areas of variable compression ratio, variable spark timing and operation with any combustible fuel. The net electrical power output is measured by a DC ammeter and volt-meter. Run it on ethanol or methanol, propane or natural gas and measure the horsepower with the electric as shown above and witness the actual combustion of different fuels. Available with or without and with or without electric start. With an emission analyzer you can do many alt. fuels emission tests. The program is based on Alternative Fueled Engine technology for the 21st century.
