ADVANCING COMPUTATIONAL HYDROACOUSTICS FOR MARINE PROPELLERS: INVESTIGATING THE LIMITS OF INCOMPRESSIBLE SOLVERS IN FAR-FIELD NOISE PREDICTION

Advancing Computational Hydroacoustics for Marine Propellers: Investigating the Limits of Incompressible Solvers in Far-Field Noise Prediction

As sound is a propagating pressure wave, it is important to obtain the hydrodynamic pressure oscillations in the fluid to calculate propeller noise.Numerical hydroacoustic simulations generally assume incompressible flow.Time delays in sound propagation are neglected due to the incompressibility assumption, leading to physically infeasible results

Pilot use of a novel smartphone application to track traveller health behaviour and collect infectious disease data during a mass gathering: Hajj pilgrimage 2014

This study examines the feasibility of using a smartphone application (app) to conduct surveys among travellers during the Hajj pilgrimage, where the Combs use of apps has not been evaluated for infectious disease surveillance.A longitudinal study was conducted among pilgrims at the Hajj 2014 using an iPhone app with separate questionnaires for thr

Polarization-controlled chiral transport

Abstract Handedness-selective chiral transport is an intriguing phenomenon that not only holds significant importance for fundamental research but also carries application prospects in fields such as optical communications and sensing.Currently, on-chip chiral transport devices are static, unable to modulate the output modes based Tooth Box on the
