Numerical simulation of isothermal cruciform jet flow

Abstract

This paper presents the results from numerical simulation of jet flow emanating from a cruciform orifice. OpenFOAM is used for the simulations with RANS standard k-ε turbulence model. The results are validated with the experimental data of Quinn [1]. Mean flow quantities and turbulent quantities are discussed in detail. The evolution of cruciform shape to circular shape is described with various contours of mean flow and turbulent quantities. Possible reasons for the evolution of cross sectional shapes are discussed.
