Abstract Fault-karst reservoirs are featured by complex geological characteristics, and accurate fast simulation of such kind using traditional simulator methods is pretty hard. Herein, we tried to discrete the fault-karst structures into one-dimensional connected units connecting well, fracture cave based on reservoir static physical parameters injection-production dynamics. Two characteristic...

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...

Needle-free jet injections are actuated by a pressure impulse that can be delivered different mechanisms to generate high-speed jets (Vj~O102 m/s). During filling and transportation of disposable cartridges ampoules, bubbles form, which problematic especially for viscous fluids. Here, we report on the effect location size entrapped air pockets in used spring-powered injections. As pass through ...

The mixture formation prior to the ignition process plays as a key element in the diesel combustion. Parametric studies of mixture formation and ignition process in various injection parameter has received considerable attention in potential for reducing emissions. Purpose of this study is to clarify the effects of injection pressure on mixture formation and ignition especially during ignition ...
