High Order Numerical Simulation of Sound Generated by the Kirchhoff Vortex
An improved high order nite di erence method for low Mach number computational aeroacoustics (CAA) is described. The improvements involve the conditioning of the Euler equations to minimize numerical cancellation errors, and the use of a stable non-dissipative sixth-order central spatial interior scheme and a thirdorder boundary scheme. Spurious high frequency oscillations are damped by a third...

متن کاملHeat Transfer from a Tube Bank in Cross Flow in a Duct
An experimental investigation on heat transfer coefficient is presented from three horizontal tubes in a vertical array in a duct for 500<ReD<6000. A mass transfer measuring technique based on psychrometry chart is used to determine heat transfer coefficient. The diameter of the tubes is 11 mm each spaced 40 mm apart and in-line pitch ratio varies 
in the range 0.055<D/W<0.22. The experimen...

متن کاملSound pressure level generated by individual portable sound equipment.
INTRODUCTION The use of Personal Digital Audio Players can cause hearing injuries, as the sound is generated directly in the ear canal. It is believed that different types of headphones can cause different amplifications, since they cause changes in the volume and resonance of the ear canal according to their depth. OBJECTIVE This study aimed to determine the sound pressure to which young ind...
