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…
Numerical anisotropy study of a class of compact schemes
Adrian Sescu, Ray Hixon
We study the numerical anisotropy existent in compact difference schemes as applied to hyperbolic partial differential equations, and propose an approach to reduce this error and t…
Numerical Anisotropy in Finite Differencing
Adrian Sescu
Numerical solutions to hyperbolic partial differential equations, involving wave propagations in one direction, are subject to several specific errors, such as numerical dispersion…
Combined prefactored compact schemes for first- and second-order derivatives: conceptual derivation
Adrian Sescu
The derivation of combined prefactored compact schemes for first and second order derivatives is described here, relying on the Fourier analysis of the original prefactored compact…
