DOI: 10.1002/fld.4337
Abstract: Summary In this paper, we propose a simple robust flux splitting method for all-speed flows with low dissipation. Following the Toro-Vazquez splitting, the inviscid flux is split into the convective and the pressure parts first.… read more here.

DOI: 10.1103/physrevb.99.235405
Abstract: We propose that bulk free carriers in topologically trivial multivalley insulators with nonvanishing Berry curvature can give rise to low-dissipation edge currents, which are squeezed within a distance on the order of the valley diffusion… read more here.

DOI: 10.1103/physreve.96.012151
Abstract: The low-dissipation model and the endoreversible model of heat engines are two of the most commonly studied models of machines in finite-time thermodynamics. In this paper we compare the performance characteristics of these two models… read more here.
