This course is focused on description and analysis of heat transfer phenomena in different types of chemical-engineering systems. Theories of heat conduction, heat convection transport and radiation heat transport are presented. Various practical problems related to chemical-engineering applications are solved, e.g., heat conduction in planar or cylindrical walls, conduction in ribs, unsteady and multiple-dimension conduction, convection heat transfer connected with forced convection in confined and unconfined systems, heat transfer in buoyancy-driven flow and in turbulent flow, heat transport in boiling and condensation processes, radiation heat transport among black bodies.

Last update: Přibyl Michal prof. Ing. Ph.D. (30.09.2013)

The students will able to:

develop mathematical description of heat transfer in systems with heat conduction, convection and radiation.

solve engineering problems related to heat transfer by means of analytical and numerical tools.

analyze reaction-transport phenomena in chemical=engineering systems.

qualitatively design typical heat transfer systems: heat exchangers, heat insulations, dryers, boilers and other systems.
