Abstract:

The k-ω Shear Stress Transport (SST) turbulence model, one of the best eddy viscosity models with comprehensive performance, has been widely used in recent years. However, with the increase of problem complexity and simulation accuracy requirements, the standard SST turbulence model shows clear limitations in certain aspects, eliciting extensive improvement research. This paper reviews the improvement research of the SST model from six aspects: rotation/curvature effect, compressibility effect, shock wave unsteadiness effect, effect of anisotropy Reynolds stress, effect of stress-strain deviation, and laminar/turbulent transition effect. Meanwhile, it also briefly introduces the model improvement based on the data-driven technology in recent years, sorts out the ideas and development trends of various improvement research, expounds their applicability and limitations, and analyzes the reasons and problems affecting the improvement effect. Finally, some suggestions for future work are given.

Key words: turbulence model, SST, rotation/curvature, compressibility, shock wave unsteadiness, anisotropy Reynolds stress, laminar/turbulent transition
