Abstract
This paper deals with design method for thermal-fluid interaction problem by topology optimization. A design problem of a flow channel in a heat exchanger is formulated as the optimization problem for maximization of heat transfer. For the topology optimization, the governing equations of thermal and fluid fields are modified based on Navier-Stokes and heat transfer equations. Using design examples of flow channel in heat exchangers, it is shown that the distinct and complicated topology corresponding to heat conditions can be obtained.
