Learning activities and methodology
The methodology will combine lecture classes for presentation of the fundamentals with problem solving sessions. 3 of the laboratory sessions, to take place in the computer room, are designed to provide a brief introduction to CFD, to enable students to use FLUENT for solving realistic flow problems. One of the lab sessions will consist of hands-on work in the lab to take measures in a real problem and then use dimensional analysis.
