Design Sensitivity Analysis and Topology Optimization of Thermal Systems Considering Convection Heat Transfer

대류를 고려한 열전달 시스템의 민감도 해석 및 위상 최적 설계

This paper presents the adjoint variable design sensitivity analysis for thermal systems considering both conduction and convection heat transfer. Both nodal temperature and total heat flow are considered to be objective functions and design sensitivity formulas are derived for each case. For the case of convection heat transfer, the adjoint analysis is carefully proceeded to obtain a precise result. A topology optimization example is examined for a simple planar square plate in order to design a heat exchanger as verification.
