A220 Evaluation of Thermal Boundary Condition Effects on Natural Convection Heat Transfer using Adjoint Numerical Analysis

Abstract

A sensitivity analysis based on adjoint formulation is proposed to generally evaluate the thermal boundary condition effects on convection heat transfer characteristics. An illustrative example is presented for natural convection heat transfer between horizontal concentric cylinders. The sensitivity function obtained from the adjoint computation enables us to predict the change of total heat transfer rate for arbitrary thermal boundary perturbations on both inner and outer walls.
