Abstract
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.
Satisfactory agreement between thermograms and numerically obtained
temperature fields has been achieved. Based upon the 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 the 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 different temperature distributions.
