Electroheat 1

The course is a substitute for:

Electrical Heat 1 (15ET1)

Lecturer:

Tutor:

Supervisor:

Department of Electroenergetics

Synopsis:

The aim of the course is to master heat transfer laws and apply them in resistance heating devices design. The overview of the field of arc and special devices discussed. Theory of the electromagnetic field in real dielectric allows to design basic dielectric and microwave-based appliances. Theory of the thermal comfort of a human being allows the students to design electrical heating systems in interiors.
