Height-Dependent Rotor Noise and Thrust in Urban Air Mobility: An Experimental Study
Qiyu Huang, Jingwen Deng, Zishuo Lin +1
The present study investigates the aerodynamic and aeroacoustic characteristics of a propeller operating under varying rotational speeds (RPM) and heights ("H" ), with a particular…
Analysis and prediction of noise from installed subsonic chevron jets
Hasan Kamliya Jawahar, Benshuai Lyu, Mahdi Azarpeyvand
An experiment is conducted to investigate the effects of chevrons on installed subsonic jet noise at a Mach number of 0.5 using the NASA SMC000 (round) and SMC006 (chevron) nozzles…
Sound absorption in Hilbert Fractal and Coiled Acoustic Metamaterials
Gianni Comandini, Codor Khodr, Valeska Ting +2
We describe here a class of acoustic metamaterials with fractal Hilbert space-filling and coiled geometry with equal tortuosity for noise mitigation. Experiments are performed usin…
An Investigation On Neck Extensions For Single and Multi-Degree Of Freedom Acoustic Helmholtz Resonators
Abhishek Gautam, Alper Celik, Mahdi Azarpeyvand
The effect of neck extensions in single and multi-degree of freedom Helmholtz resonator based acoustic liners is studied both experimentally and numerically and the resulting trans…
Double Degree of Freedom Helmholtz Resonator Based Acoustic Liners
Abhishek Gautam, Alper Celik, Mahdi Azarpeyvand
A numerical and experimental study on double degree of freedom Helmholtz resonator based acoustic liners is performed in this paper, with the motivation to improve the understandin…
On the noise prediction for serrated leading edges
Benshuai Lyu, Mahdi Azarpeyvand
An analytical model is developed for the prediction of noise radiated by an aerofoil with leading edge serration in a subsonic turbulent stream. The model makes use of the Fourier…
Prediction of noise from serrated trailing-edges
B. Lyu, M. Azarpeyvand, S. Sinayoko
A new analytical model is developed for the prediction of noise from serrated trailing-edges. The model generalizes Amiet's trailing-edge noise theory to sawtooth trailing-edges, r…
Acoustic interaction forces and torques acting on suspended spheres in an ideal fluid
J. Henrique Lopes, M. Azarpeyvand, G. T. Silva
In this paper, the acoustic interaction forces and torques exerted by an arbitrary time-harmonic wave on a set of N spheres suspended in an inviscid fluid are theoretically analyze…
