Numerical Investigation of a Rectangular Jet Exhausting over a Flat Plate with Periodic Surface Deformations at the Trailing Edge
Colby Horner, Adrian Sescu, Mohammed Afsar +1
In an attempt to reduce jet noise, blended wing concept vehicle utilizes rectangular jet exhaust ports exiting from above the wing ahead of the trailing edge. In this study, we tak…
Investigation of wakes generated by fractal plates in the compressible flow regime using large-eddy simulations
Omar Es-Sahli, Adrian Sescu, Mohammed Z. Afsar +1
We investigate flows interacting with a square and a fractal shape multi-scale structures in the compressible regime for Mach numbers at subsonic and supersonic upstream conditions…
Effect of non-parallel mean flow on the acoustic spectrum of heated supersonic jets: explanation of `jet quietening'
Mohammed Afsar, Adrian Sescu, Vasileios Sassanis
Noise measurements of heated axisymmetric jets at fixed supersonic acoustic Mach number indicate that the acoustic spectrum reduces when the temperature ratio increases. The `spect…
Large eddy simulation study of the humidity variation in the shadow of a large wind farm
Adrian Sescu, John Haywood, Kevin Adkins
Numerous studies have shown that wind turbine wakes within a large wind farm bring about changes to both the dynamics and thermodynamics of the atmospheric boundary layers (ABL). P…
Modeling and prediction of the peak radiated sound in sub-sonic axisymmetric air jets using acoustic analogy based asymptotic analysis
Mohammed Z. Afsar, Adrian Sescu, Stewart. J. Leib
This paper uses asymptotic analysis within the generalized acoustic analogy formulation (Goldstein. J. Fluid Mech 488, pp. 315-333, 2003) to develop a noise prediction model for th…
Wakes in stratified atmospheric boundary layer flows: an LES investigation
John S. Haywood, Adrian Sescu
Large eddy simulations and three-dimensional proper orthogonal decomposition were used to study the interaction between a large stationary and moving bluff body and a high Reynolds…
