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.

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.

To obtain an assessment, a project has to be submitted and the examination test must be completed at a minimum of 50% of the score. To complete the oral exam, the student must successfully answer two questions from the list of questions. The resulting mark is calculated as an arithmetic mean of the results of the examination test and the oral part of the exam.
