...Takayuki Yamada; Kazuhiro Izui; Shinji Nishiwaki This paper proposes an optimum design method, based on our level set-based topology optimization method, for maximizing thermal diffusivity in problems dealing with generic heat transfer boundaries that include design-dependent boundary conditions...

... a computational two dimensional heat transfer distribution model inside the reactor in order to validate our optical results. The combined simulation results show that correctly varying the aperture diameter with respect to transient incoming solar flux densities facilitates the maintenance of quasi-constant...

...Lin Zhu; Tien-Chien Jen; Xiao-Ling Kong In this paper, the influences of low heat transfer condition at the outer walls on the microcombustor are investigated due to the fact that a sufficiently small heat transfer coefficient at the outer wall incurs the upstream burning in the recirculation...
