Heat Transfer Analysis of Heating Plate with Multiple Heat Sources
In the paper the 3D numerical study of transient heat transfer phenomenon on a solid plate with complex heat sources has been carried out. In order to validate the chosen numerical model, a set of thermographic measurements have been performed on a heating plate sample. The infrared camera provided a number of thermograms showing the development of transient temperature fields on the plate surface. A good agreement between thermograms and numerically obtained temperature fields has been achieved. Based upon validated numerical model, an approach involving thermographic measurements has been used to estimate the position of heat sources inside the plate. Numerically obtained temperature distributions have been used for calculation of effective transient heating output. The unsteady behavior of heating plate with complex heat sources has been numerically studied for different plate materials. It has been concluded that the temperature fields and transient heating outputs depend on physical properties of the plate material. However, when a steady state has been achieved, different plate materials give equivalent steady heating outputs despite of different temperature distributions.
