A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...
A PM0.1 personal sampler devised by the authors (Furuuchi et al., 2010a) was investigated into its performance for the practical application, or on an improvement for a smaller cut-off size and also the removal of coarse particles using pre-cut impactors. The pressure drop through the inertial filter was discussed along with the separation performance since it is important to use a portable bat...
The radiation of sound from a perfectly expanded Mach 2.5 cold supersonic jet of 25.4 mm exit diameter flowing through a partially open rigid-walled duct with an upstream i-deflector has been studied experimentally. In the experiments, the nozzle is mounted vertically, with the nozzle exit plane at a height of 73 jet diameters above ground level. Relative to the nozzle exit plane (NEP), the loc...
