EXPERIMENTAL INVESTIGATION OF THE TRANSIENT JET EMANATING FROM THE PROTOTYPE DIRECT GASEOUS INJECTOR [PDF]
مجله مدل سازی در مهندسی, 2011 In this paper high speed Schlieren method was employed for measurement of the geometrical characteristics of transient gaseous jet. Axial jet penetration and its angle versus time were calculated in pressure ratios of 2, 3 and 4 and three different ...

Variation of turbulent burning rate of methane, methanol, and iso-octane air mixtures with equivalence ratio at elevated pressure [PDF]
, 2005 Turbulent burning velocities for premixed methane, methanol, and iso-octane/air mixtures have been experimentally determined for an rms turbulent velocity of 2 m/s and pressure of 0.5 MPa for a wide range of equivalence ratios. Turbulent burning velocity

Growth of shocked gaseous interfaces in a conical geometry [PDF]
, 2003 The results of experiments on Richtmyer-Meshkov instability growth of multimode initial perturbations on an air-sulfur hexafluoride (SF6) interface in a conical geometry are presented. The experiments are done in a relatively larger shock tube.

Hybrid Sindbis/Epstein-Barr virus episomal expression vector for inducible production of proteins
BioTechniques, 2005 Alphavirus vectors are attractive as recombinant protein expression systems due to the high level of gene expression achieved. The combination of two mutations in the viral replicase, which render the replicase noncytopathic and temperature-sensitive ...
