The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

Transport model of droplets injected axially or transversely into a plasma jet is presented. The droplets contain a ceramic precursor that precipitates in the vaporizing droplets. Droplet temperature and solute concentration distributions were predicted to estimate precipitation zones based on a homogeneous nucleation hypothesis. Effects of droplet size, injection velocity and injection angle w...

A Magneto Plasma Sail (MPS) produces a propulsive force by the interaction between the solar wind and an artificial magnetic field inflated by a plasma jet injection. Using a 2D hybrid PIC simulation code, the parametric study of magnetic inflation by the plasma jet injection is performed under different realistic parameters in terms of plasma material (Ar/Xe) and injection direction. We evalua...

in the present work, the simultaneous effects of fuel injection rate and injection of air jet into the combustion chamber on exhaust emissions, combustion process and performance parameters in a direct injection diesel engine were investigated. in order to create an air jet, a design was presented in which a secondary chamber (air cell) was created inside the cylinder and was joined to the main...

designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied together with design and build a low-speed wind tunnel. a specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. there are generally three regi...

We link the lack of FR I type structure among quasars to the void of radio loud quasars below a critical disk luminosity of 10 46 erg/sec in the PG sample. We argue that the opening angle of the obscuring torus in radio loud quasars depends on the power of the central engine, approaching the jet's beaming angle near the FRI/FR II break. Consequently, low power radio quasars would either be clas...

The X-ray light-curves of the GRB afterglows monitored by Swift display one to four phases of powerlaw decay. In chronological order they are: the burst tail, the ”hump”, the standard decay, and the post jet-break decay. We compare the decay indices and spectral slopes measured during each phase with the expectations for the forward-shock model to identify the processes which may be at work and...

We link the lack of FR I type structure among quasars to the void of radio loud quasars below a critical disk luminosity of ∼ 10 erg/sec in the PG sample. We argue that the opening angle of the obscuring torus in radio loud quasars depends on the power of the central engine, approaching the jet’s beaming angle near the FR I/FR II break. Consequently, low power radio quasars would either be clas...
