A topology optimization method for rarefied gas flows

open access: yesNihon Kikai Gakkai ronbunshu, 2017
We construct a topology optimization method for two dimensional rarefied gas flow problems, based on level-set boundary expressions. The degree of rarefaction is expressed by the Knudsen number, which is the ratio of the mean free path and the ...
