Numerical analysis of flux and losses in straight and circular grating
Numerical investigation of flow and losses has been done for vast selection of flow angles in 2D-blades. CFD calculation was done in Fluent 6.3 and Ansys CFX 11. RANS equation supplemented with sst k-w turbulence model was used for numerical calculation. A good concordance of the calculation and experimental data was reached. When the inlet flow angle is negative losses are distributed quite uniformly along 2d-blade cannel. When the inlet flow angle has great negative value there is a big gradient of the losses near leading edge. The results allow us to prompt this model for investigation of flow and losses in 2d-blades.
