Abstract

In this paper we present preliminary results from a high-resolution large eddy simulation (LES) study which will establish whether jet inlet velocity conditions are of significance in separation control applications. We include inlet pipe geometry, in order to allow realistic turbulent structures to naturally develop. Ultimately, we will simulate various momentum thicknesses, (D=q = 50, 80, 120 and 180) at Re_j = 10⁴ where Re_j =U_jD=n, where U_j is the jet inflow velocity and D is the jet diameter, however this paper presents initial high-resolution LES results for a steady jet, Re_j = 10⁴, D=θ = 50. The ≈ 6×10⁶ cell model was computed using our local Beowulf cluster at Curtin University, (12× Intel i7 920 quad core CPUs, = 48 cores). Our results show promising agreement with validation data, and indicate that our model has the potential to produce useful and accurate data regarding the evolution of a steady turbulent jet issuing into quiescent air.
