Results of Planar Cascade Blades

This study presents three design cases for planar cascade blades using an adjoint method. The cases include optimal design of entropy generation, inverse design of exit flow angle distribution, and inverse design with another target stagger distribution. The design parameters and analysis results are shown through various figures.

  2. Three Design Cases by Using an Adjoint Method Case 1 Optimal design of entropy generation with constraint cost function: where entropy generation per unit flow mass; and mass-averaged exit flow angle for whole exit the target exit flow angle; and Case 2 Inverse design of exit flow angle distribution cost function: where mass-averaged exit flow angle distribution the target exit flow angle distribution Case 3 Inverse design of exit flow angle distribution with another target stagger distribution Design parameters for the three design cases: stagger angle distribution
