personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. this work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. velocity profiles have been measured around and within typical cylindrical sampling devices, plac...

this study presents a computational study of mixture formation, flame front movement, combustion process and emission formation at the various spray angles and number holes in a direct injection diesel engine. this work is carried out in a direct injection om355 diesel engine at four and five holes with 130
, 135
and 140
spray angles. the amount of fuel injected per cycle is constant at all s...

the effect of partial slip and temperature dependent fluid properties on the mhd mixed convection flow from a heated, non-linearly stretching surface in the presence of radiation and non-uniform internal heat generation/absorption is investigated. the velocity of the stretching surface was assumed to vary according to power-law form. thermal transport is analyzed for two types of non-isothermal...

The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...

force convection heat transfer of turbulent nano fluid flow in 90 and 60 degree elbow is simulated by using fluent. single phase model has been implemented to study such a flow field and standard
