The methodology will combine lecture classes for presentation of the fundamentals with problem solving sessions. The laboratory sessions, to take place in the computer room, will consist of a crash course on CFD methods to enable students to use FLUENT for solving realistic flow problems. The evaluation of the laboratory sessions will be based on an individual CFD project in which the student will be asked to address the optimized design of a simple flow system.
