Single-Course English 5 ECTS

Heat and Mass Transfer

Overall Course Objectives

To give a theoretical and practical background to formulate and solve problems within heat transfer systems. Furthermore, evaluate different methods of solution in engineering context.

Learning Objectives

  • Understand and explain how the physical laws are incorporated in conduction, convection and radiation.
  • Demonstrate how to solve practical engineering problem concerning heat transfer.
  • Make energy balances to determine the boundary conditions for systems with combined heat transfer by conduction, convection and radiation for both analytical and numerical problems.
  • Determine temperature profiles in simple construction in rectangular- cylindrical- and spherical coordinate systems with and without heat generation in the system, and setting up the boundary- and initial conditions.
  • Understand, explain and calculate the different types of convections including natural, forced, boiling and condensation.
  • Calculate heat transfer for natural- and forced convection for plane surfaces and for flow around pipes and spheres.
  • Understand, explain and calculate on heat exchangers by using LMTD- and NTU method.
  • Calculate heat transfer by radiation between diffuse, gray and opaque surfaces by using the Matrix-method and solving by EES.
  • Have knowledge about mass transfer and Fick’s law, and the analogy to heat transfer.
