Designing and Manufacturing the Multiple Jets Simulator and Experimental Investigation of the Multiple Jets in Crossflow
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...
متن کاملBlue jets and gigantic jets
An overview of general phenomenology and proposed physical mechanisms of large scale electrical discharges termed ‘blue jets’ and ‘gigantic jets’ observed at high altitude in the Earth’s atmosphere above thunderstorms is presented. The primary emphasis is placed on summarizing available experimental data on the observed morphological features of upward jet discharges and on the discussion of re...

متن کاملExperimental Study of Parallel Jets Scouring, considering the effect of jets distance on erosion rate
The scouring process at downstream of the hydraulic structures is a complex phenomenon and many parameters affecting its amount. Failure to control this phenomenon causes damages to the dam and its associated hydraulic structures. In this research, the scouring caused by the combination of jets outlet from a gated spillway was investigated experimentally and the combination of jets adjacent to ...
متن کاملTemporal and Angular Properties of GRB Jets Emerging from Massive Stars
We study the long-term evolution of relativistic jets in collapsars and examine the effects of viewing angle on the subsequent gamma ray bursts. We carry out a series of high-resolution simulations of a jet propagating through a stellar envelope in 2D cylindrical coordinates using the FLASH relativistic hydrodynamics module. For the first time, simulations are carried out using an adaptive mesh...
