Heat and Mass Transfer

The course intends to give an introduction to the laws for heat and mass transport. Following an introduction to the principles of heat transfer, are these topics addressed: Stationary and non-stationary conduction, basic conditions and engineering contexts of convective heat transfer, phase change heat transfer (boiling/condensation), radiation and heat exchangers. Both analytical and numerical (computer-based) calculation methods are presented.

Knowledge:The course will give the student knowledge of- basic heat transfer mechanisms (conduction, convection, radiation).- heat transport by conduction in solids for stationary and transient conditions.- heat transport by convection in duct flow and on external surfaces.- heat transfer by radiation.- convective mass transport.- friction and pressure loss in boundary layer flow in ducts and onexternal surfaces.- heat transfer by phase change (boiling/condensation).- boundary layer flow, laminar and turbulent flow.- heat exchangers: behavior and the most common designs.Skills:The course will enable the student to- calculate heat transfer by conduction, convection, and radiation forpractical situations.- analyze and calculate heat transport in composite systems withseveral heat transfer mechanisms involved.- calculate mass transport using a heat transfer analogy.- perform thermal-hydraulic calculations for heat exchangers.General competence:The course will provide the student with- basic competence included in other topics focusing on thermalenergy systems and processes.- skills to analyze and calculate heat transfer incomplex problems and heat engineering equipment

Lectures, calculation exercises, computer exercises, and laboratory exercises. A minimum of 75 % of the calculation/computer exercises, as well as at least 1 of the laboratory exercises, has to be approved before the student can take the exam. It can be arranged approximately 2 mid-term tests, which will each be credited as 2 approved exercises.Compulsory laboratory work and exercises.
