The goal To introduce the basic laws of heat transfer and energy transfer by the mass transfer.Understanding the temperature as the major limiting factor of the power of electric power component.Understanding the distribution of the losses, consequent distribution of the heat and the temperature increase.Introducing practical approach to perform the thermal calculations based on empirical laws.
The outcome To train students to (1) identify,formulate and solve basic heat transfer problems appearing in practice of electric power engineering,(2) to understand how the basic laws can be applied in the practice,but also to be aware of empirical procedures and (3) to understand the new possibilities of modern software tools and the methods,based on more rigorous and detailed physical models.
