The objective of this study is to develop models for the subgrid-scale (SGS) stress and the SGS scalar flux by applying the same kind of methodology that leads to the explicit algebraic Reynolds stress model, EARSM [2], and the explicit algebraic scalar flux model, EASFM [3], for RANS. The idea is that these new models can improve the description of the anisotropy compared to eddy viscosity models. Since the new models can include the effect of system rotation in a natural way they have a particular potential for rotating flows.
