| Abstract: |
| High efficiency thermal design and control is one of the most interested points in the field of high power continuous microwave wireless energy transfer and space solar power station (SSPS), which has attracted great attention and interest from experts all over the world. Based on topology optimization and bionics, a new thermal design methodology is proposed to face the challenge of thermal control in SSPS via orb-shape membrane energy gathering array (SSPS-OMEGA). Firstly, an optimization model is established to minimize the surface average temperature and flow channel pressure loss by combining the fluid flow outlet boundary and flow channel configuration, and the optimal outlet position and topological configuration of the flow channel of gyro photovoltaic back panel are obtained, by which the heat transfer efficiency can be improved obviously. Secondly, the layout and topology optimization model of free-space radiative heat dissipation is developed by analogy with the shape and structure of butterfly wings, and the radiative efficiency could be improved to a certain extend whilst satisfying the nonlinear behavior constraints. Furthermore, the sensitivity of the nonlinear objective and constraint functions with respect to design variables are mathematically deduced. Finally, several numerical experiments are given to demonstrate the strategy, model and method proposed in this manuscript. |
