Theoretical and numerical approaches of a plane, laminar and non-confined, impinging jet

Abstract

We propose in this paper, a numerical study of a planar impacting jet flow. The flow is assumed isothermal, laminar and unconfined. The developed computer code is based on the finite volume method, which was used to discretize the N-S equations. The code allowed us to simulate the physical phenomenon’s taking place in the jet flow. The work focuses, on the description of the evolution of the jet and the presentation of the different characteristics of the flow, for different values of the Reynolds number and the impacting height. Calculations were made for values of the Reynolds numbers ranging from 0.01 to Re = 2000, i.e. in the limits of laminar flow regime, and for values of the ratio between the height of the outlet nozzle-impact surface of 0.1 to 20. The theoretical and numerical approaches of this work are confronted with the experimental works of Sholtz et al., [2].
