Inverse design and control of microstructural development in solidification processes with natural convection
- Cornell Univ., Ithaca, NY (United States). Sibley School of Mechanical and Aerospace Engineering
This paper presents a finite element solution of an inverse solidification design problem. It is based on the previous work on an adjoint method with a functional optimization scheme for the solution of inverse thermal convection problems with overspecified thermal boundary conditions. An inverse calculation is performed here for directional solidification processes to find the optimal heat flux at the mold wall boundary on both the solid and liquid mold sides. The objective is to achieve desired velocity and heat flux histories at the solid-liquid interface. The specification of the growth velocity and freezing interface heat fluxes considers the microstructural implications on the casting product and the morphological stability requirements of the freezing interface. An example of solidification in a rectangular mold with a planar interface growth is shown.
