Optimal Design of Two-Dimensional Cascade with Shock-Free Inflow Criterion
Muis, Abdul,Sutikno, Priyono,Soewono, Aryadi,Hartono, Firman Korean Society for Fluid machinery 2016 International journal of fluid machinery and syste Vol.9 No.4
The shock-free inflow criterion applied in the development of two-dimensional cascade for turbomachinery design. The developed cascade analysis with potential flow calculation through a panel method has been used to determine the shock-free inflow condition. The combination between cascade analysis and PSO (particle swarm optimization) algorithm provides an opportunity to develop a diagram of a two-dimensional parameter cascade at various airfoil shapes. Analytical equations have been derived from the diagram that will facilitate the turbomachinery designer in applying the shock-free inflow criterion on their developed cascade. This method has been used to develop the very low head axial hydraulic turbine and provides excellent results of numerical and actual prototype performances.
