SST (Menter’s Shear Stress Transport)
SST (Menter’s Shear Stress Transport) turbulence model is a widely used and robust two-equation eddy-viscosity turbulence model used in Computational Fluid Dynamics. The model combines the k-omega turbulence model and K-epsilon turbulence model such that the k-omega is used in the inner region of the boundary layer and switches to the k-epsilon in the free shear flow.
SST is a humanist sans-serif typeface designed by Monotype for Sony. It supports the Latin, Greek, and Cyrillic alphabets and has matching styles for Thai, Hebrew, Japanese and Arabic. It is modelled after Helvetica (Sony’s previous typeface) and Frutiger. SST is used on Sony’s product packaging, operating instructions, websites, TV menus, in Playstation 4 and on the Xperia smartphone.
