A great deal of progress has been made in the modeling of aerodynamically generated
sound of rotors over the past decade. Although the modeling effort has focused on helicopter …

This article provides a critical review of computational techniques for flow-noise prediction
and the underlying theories. Hybrid approaches, in which the turbulent noise source field is …

Each modern industrial process environment needs sensors to detect the physical quantities
involved (eg, electric current, mechanical torque, temperature, etc.), a signal-conditioning …

This chapter presents an introduction to multiscale and stabilized methods, which represent
unified approaches to modeling and numerical solution of fluid dynamic phenomena. Finite …

This contribution benchmarks the aeroacoustic workflow of the perturbed convective wave
equation and the Ffowcs Williams and Hawkings analogy in Farassat's 1A version for a low …

THE problem of noise generated by turbulent ows over structures is important in the design
of submarines, surface ships, airplanes, and automobiles. A canonical problem that occurs …

The analytical model of the trailing-edge noise of an airfoil derived in the first part of this
study is assessed by first comparing the predictions with alternative analytical and numerical …

We present a finite element (FE) formulation of Lighthill's acoustic analogy for the hybrid
computation of noise generated by turbulent flows. In the present approach, the flow field is …

The hybrid aeroacoustic approach is an efficient way to address the issue of the disparity of
scales in Computational AeroAcoustics (CAA) at low Mach numbers. In the present paper …

The aerodynamic noise of the axial compressor is one of the significant noise sources of gas
turbines, and it has gradually attracted the attention of the majority of researchers. In this …
