BROADBAND SUPPRESSION OF AERODYNAMIC PRESSURE ON THE HIGH-SPEED BLUFF BODY SURFACE WITH PERIODIC SQUARE-CAVITY ACOUSTIC METASURFACE

Broadband suppression of aerodynamic pressure on the high-speed bluff body surface with periodic square-cavity acoustic metasurface

In this paper, a Multiphysics coupling simulation model of veuve ambal rose flow and acoustics is proposed using COMSOL software, and its results are verified by comparing with experimental results of others.Then, the aerodynamic pressure above the bluff body surface at a speed of 350 km/h is simulated.Moreover, a near-zero-impedance acoustic metas

Estimation of generator electrical power output and turbine torque in modelling and field testing of OWC wave energy converters

The oscillating water column is one of the most tested and used wave energy converter types.It requires the use of an air turbine connected to an electrical generator.The deep understanding of all physical quantities of the energy chain components is based on transducers.The electrical generator efficiency is a key input to wave-to-wire numerical m
