Report on code development (D19)

Within the EU-funded 5FP project, Leading Edge, Helsinki University of Technology (HUT) has implemented an Explicit Algebraic Reynolds Stress Model in its Reynolds-Averaged Navier-Stokes equation solver FINFLO. The EARSM is linked with the k-omega turbulence model. Two test cases are presented, the flow over a flate plate and the flow in a rectangular duct. Finally a comparison is made between the three turbulence models, k-epsilon, k-omega and the EARSM on the calculation of the flow patterns of a highly skewed propeller in open water conditions at model scale. While the k-omega model and the EARSM gives satifactory results, it is found that the k-epsilon model gives more accurate results concerning both the torque and the thrust coefficients compared with experimental values.
