Boundary layer theory: Velocity, temperature and concentration profiles. Heat and mass transfer coefficients. Nusselt and Sherwood correlations. Two and three fold analogies. Liquid metals with low Prandtl numbers. Turbulent transport. Reynold's analogies. Chemical reaction kinetics at phase boundaries.
Channel flow: Entrance and fully developed flow regimes.
Particles, drops and bubbles: Terminal motion. Heat and mass transfer.
Packed beds: Ergun's formula for pressure loss. Heat and mass transfer. Fluidisation.
Thermal radiation: Emission, absorbtion, reflecton. Adiabatic surfaces.Radiation in multi surface systems, view angle factors.

Learning outcome

The subject gives the students of Material Technology a thorough introduction to heat and mass transfer in metallurgical processes with emphasis on boundary layer theory, particle technology and thermal radiation.

Learning methods and activities

Lectures, exercises and laboratory exercises. Lectures will be given in English. Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (50%), a midterm test (30%) and exercises (20%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. If there is a re-sit examination, the examination form may be changed from written to oral.
