Vortical Structures of an Impinging Jet in Cross-flow
The analysis of an impinging jet in a cross-flow and the resulting vortical structures are presented. A computational fluid dynamics simulation utilizing the k-ε model for turbulence is validated in COMSOL Multiphysics® by comparing the results to previous experimental and theoretical studies conducted in air. The model was then altered utilizing the hydraulic analogy for an experiment planned within a water tunnel that will maximize the visualization capabilities of the secondary flows that develop. Solutions to this hydraulic version of the computational fluid dynamic model were completed in both steady and time dependent states. The results were examined through non-dimensionalized comparisons of the velocity components to previous work, steady state cross-sectional data throughout the computational domain, and time dependent data. The features of the flow structures and insight into the physics that form them are established.
