Conduction analysis of Single Material Sphere


Thermal conduction is the transport of energy in a medium due to a temperature gradient and the physical mechanism is that of random  atomic or molecular activity.The quantity of heat flow through the cross sction of a solid body over time 't' in steady state is governed by the Fourier's law of heat conduction

Working Formula

Heat conduction through single material sphere is given by


                                       Where the symbols carry their usual meanings



radial conduction unit

It consist of-

1.      Insulating housing with disc and lid

2.     Heater

3.     cooler

-The heater is fixed in the center of the bress disc.

-There is Cu pipe around the disc through which cooling water flows.

-From above,6 temperature measuring points are fitted.

-These points stretches radially from the center to the periphery.

The control and dispaly unit has a digital temperature and power dispaly
