Fluid flow and Heat Transfer, Advanced Course

Conservation equations: Conservation equations for global mass, momentum, energy and chemical components in fluid mixtures. Dimensional analysis.

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 velocity.

Packed beds: Ergun's formula for pressure loss.

Numerical simulations: Introduction to Computational Fluid Dynamics (CFD).

Thermal radiation: Emission, absorbtion, reflection. Adiabatic surfaces. Radiation in multi surface systems, view angle factors.

After this course the student can:

- Identify and describe transport phenomena dominating processes for production and/or treatment of liquid metals/alloys.

- Explain various aspects regarding transport/transfer of mass, momentum, energy, and chemical components in fluid mixtures or between phases.

- Perform basic computations on transport/transfer of mass, momentum, and energy in idealized (sub-)systems, e. g. by application of boundary layer theory or correlations for energy and mass transfer.

- Choose necessary actions for incorporation of chemical reaction kinetics as well as treatment of particles, droplets and bubbles in the overall global concervation equations for mass, momentum and energy.

- Formulate and analyse problems involving radiation in multi-surface systems.

- Use methods for finding and evaluating estimates based on dimensional analysis and analogies for heat and mass transfer.

- Introduce simplifying assumptions for computations and assess the validity of the simplifications done.

- Set up simple numerical simulations in heat and mass transfer related problems.

Lectures (60 hours), exercises (30 hours) and self study (120 hours).

Lectures will be given in English and examination papers will be given in English only, while students can choose to use Norwegian or English during the oral examination and/or presentations.

50% of the exercises must be approved before the final exam as well as a written report relating to numerical simulations of heat and mass transfer.

The report will serve as a basis for an oral presentation which will account for 20% of the final grade. The presentation must be approved in order to qualify for the final exam.

Students are free to choose Norwegian or English for written assessments.
