“…Still, this work shows that the combination of the adaptive Cartesian grid and the single field implicit solution to conjugate heat transfer leads to a robust and efficient treatment of the interface. And while adaptive Cartesian grid methods have been used to simulate phase change [45,[55][56][57][58][59][60], the current work is the first application of these methods to the optimal design of LHTSDs with embedded fin structures. For such applications, the approach is attractive.…”
