Conduction analysis of Double Material Sphere



 Back to HOME



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 section of a solid body over time 't' in a 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
