Simulation of heat transfer in the program COMSOL Multiphysics
 DOLEŽAL, David
This bachelor thesis deals with the study of heat conduction in solids and the creation of a model in the commercial program COMSOL Multiphysics. The work is divided into five thematic units. The first part deals briefly with the meaning and characteristics of both the program and the heat transfer module. Heat, as one form of energy, accompanies all the physical processes we can encounter and is an integral part of our lives. In this connection, the basic physical mechanisms of heat transfer, such as conduction, flow and radiation, are presented in the second part. Attention is also paid to physical variables, theories and concepts whose knowledge is necessary to investigate heat transfer mechanisms. The third part of the thesis is devoted to the experiment, consisting in the observation of temperatures of heated materials by a thermal camera. In the fourth part of the thesis are first described in general the steps accompanying the production of the model and subsequently production of a particular model in the program itself. The last part of the thesis is devoted to comparing experimental results with data from the model.
