Résumé
Jet pumps are versatile hydraulic devices designed for displacing and/or mixing fluids. Scale-Resolving Simulations (SRS) of jet pumps are prohibitively expensive due to the presence of high Reynolds number flows and complex interactions within a wall-bounded domain. This study evaluates three SRS models to identify the most suitable approach for efficiently capturing the internal flow dynamics of jet pumps. Comparisons with experimental data reveal that while Stress-Blended Eddy Simulation (SBES) provides results comparable to Wall-Adapting Local Eddy-Viscosity (WALE) and Algebraic Wall-Modeled LES (AWMLES), it requires significantly lower computational costs. Simulation of the jet pump at various flow ratios (0.5, 1.6, and 2.16) revealed that as the flow ratio increases, the location where the primary jet breaks up due to momentum transfer with the secondary flow shifts further downstream. This finding is particularly important when the jet pump is used as a mixer, as mixing a larger amount of secondary flow with a constant amount of primary flow requires a longer device to ensure effectiveness.
