WebMay 28, 2024 · Abstract. Reynolds-averaged Navier–Stokes (RANS) approach is used to simulate the steady-state of a family of pressure-induced turbulent separation bubbles in the presence of sidewalls. Different turbulence models are employed with a specific emphasis on the baseline explicit algebraic Reynolds stress model (BSL-EARSM) and the … WebEARSM turbulent model is validated via comparison with other turbulent models and public experimental data. 1 INTRODUCTION CFD methods are recently used in many applications. They are useful especially in cases where is not a direct access for measurement tools or physical conditions are not suitable such

WebA numerical computational fluid dynamics (CFD) method was used to investigate the performance characteristics of the pump, specifically discussing internal flow conditions such as velocity, pressure and the radial force mentioned above. ... BSL EARSM model appeared to be a suitable choice for flow in single-blade centrifugal pump. WebThe flow fields are analysed using Reynolds-averaged Navier-Stokes (RANS) CFD approaches. The RANS turbulence models used in this investigation are Menter’s Shear Stress Transport (SST) and the Explicit Algebraic Reynolds Stress Model (EARSM). All experiments and simulations were run quiescently, without an external flow.
