ABSTRACTThe current study focuses on numerical investigations of narrow passage flows with impingement jets. Six different turbulence models, including linear eddy viscosity models, an explicit algebraic Reynolds stress model, and a V2f model, are explored as they are utilized with k-ϵ and k-ω platforms. The main objective is a comparison of the numerical accuracy of models as applied to the simulation of complex flows within narrow passages. Numerical results obtained with the different models are compared with the experimental data from the literature. As such, comparisons are performed for different flow field quantities, including mean velocity components, Reynolds stress tensor components, and surface Nusselt number distribution.
