文摘

A modified SST turbulence model is proposed and applied for the numerical simulations based on OpenFOAM. The influence of the magnitude of inflow acceleration in numerical simulation is investigated, and the critical acceleration value is found. The maximum transverse amplitude will be captured more accurately with modified SST model and proper inflow acceleration value.
