Description
To obtain an optimal shape, a 3D shape optimization system based on the adjoint variable method is developed. The adjoint variable method is based on the Lagrange multiplier method (a conditional variational principle), and consists of the state equation, the adjoint equation and the sensitivity equation. The equations for decreasing the fluid drag under a constant volume condition are formulated. By using the Navier-Stokes equation, the surface force located in Reynolds number 1000 can be reduced by about 57.6%, under unsteady flow. (author)
