15 صفحه اولPitot probe corrections in fully developed turbulent pipe flow
Mean flow measurements taken in fully developed turbulent pipe flow over a wide Reynolds number range are used to evaluate current methods of correcting Pitot probe data. Based on this evaluation, a new form for the displacement correction is proposed which appears to be more accurate over a wider range of conditions than those currently available. The difficulty of obtaining the true near-wall...
متن کاملNoise generation by turbulent flow in ducts
The aim of this work is to estimate the sound power generated by a turbulent flow in a duct from the knowledge of mean quantities which can be computed with a K-e turbulence model when only the plane wave can propagate, i.e., when the characteristic frequency of the turbulence is low. It does turn out to be possible for the simplest configuration of a duct free of internal obstruction. The resu...
متن کاملTurbulent Pulsating Flow through Circular Ducts
In the present paper, a numerical method has been demonstrated which works on an overall NewtonRaphson type algorithm and is capable of solving the “inverse” problem for turbulent, fullydeveloped, pulsating pipe flows, where the mass flow rate, rather than the pressure gradient is prescribed as a periodic function of time. The momentum equation, governing the transient, fullydeveloped pulsating...
متن کاملComputational Modeling and Validation of Aerosol Deposition in Ventilation Ducts
In fire models, the accurate prediction of aerosol & soot concentrations in the gas phase and aerosol & soot deposition thicknesses in the condensed phase is important for a wide range of applications, including human egress calculations, heat transfer in compartment fires, and forensic reconstructions of fires. During a fire, in addition to soot transport by advection and diffusion, a signific...
