Abstract

ABSTRACTThe current study focuses on numerical investigation of narrow passage flows with pin fin arrays. 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 of the work is to study numerical performance and accuracy of models when applied in the simulation of blade pin fin arrays. The main objective is comparison of the numerical accuracy of models, when applied for the simulation of complex flows within narrow passages. Numerical results obtained with the different models are compared to the experimental data from the literature. As such, comparisons are performed of different flow field quantities, including mean velocity components, Reynolds stress tensor components, and surface Nusselt number distributions.
