Funded PhD Project (European/UK Students Only)
The aim of this project is to study the effect of mean flow spreading on the low frequency amplification of jet noise in non axisymmetric high Reynolds number jet flows. The approach will use the generalized acoustic analogy where both mean flow and turbulence structure will be extracted from a series of Large Eddy Simulation calculations.
The PhD student will be part of collaborative team of researchers and academics from Mississippi State University and the NASA Glenn Research Center. During the second year of study, the student will be based at Mississippi. The work will involve Computational Fluid Dynamics (CFD) of jet flows using Large Eddy Simulations as well as aero-acoustic modeling using various Applied Mathematical techniques.
Reynolds Averaged Navier Stokes calculations on rectangular jets & prediction of sound using a generalized asymptotic analysis.3 months will be spent at Safran Industry at Villaroche in France.
Student will be based in Mississippi State this year conducting Large Eddy Simulation calculations
Post-processing of turbulence data & Large eddy simulation based jet noise predictions.
