The Application of 3D inverse design approach in which the blade geometry is computed for specified distribution of blade loading can lead to important breakthrough designs in turbomachinery.  In the paper, the application of the method and the process of arriving at optimum blade loading in various applications are described with reference to the flow physics.  The applications include suppression of secondary flows in mixed flow and radial impellers, suppression of corner separation in pump vaned bowl diffusers, control of cavitation in pumps and finally noise reduction in an axial flow fan is described.
