High pressure shock tube
WebJun 1, 1993 · The initial pressure has been varied between 3.2 and 42 bar and the initial temperature between 660 and 1,350 K while the equivalence ratio covers the region between 0.5 and 3.0. In dependence upon these parameters the histories of pressure and CH-band emissions at 4,315 [angstrom] show different ignition behavior. WebDec 13, 2024 · The Disadvantages of the Monotube Shock Design. The main disadvantage to a monotube is the overall length vs. stroke. For example, looking at “vintage” cars, they may have a 12” overall length shock with 4” of stroke. In a modern monotube design, you may have a 12” overall length with only 2.5” of stroke. You’ll also get a stiffer ...

WebA shock tube is an impulse reactor that generates shock waves to near-instantaneously heat a test gas. Shock tubes uniquely operate across a wide range of temperature … WebInstrumented Shock Tube Model 9901C. The 9901C uniquely characterizes pressure sensors using pressure waves created by diaphragm rupture. The reflected and incident pressures are measured. Pressure Levels - from 3 psi to over 1 000 psi (20 kPa/0.2 bar to over 6.9 MPa/69 bar) Helium or compressed air media
WebJun 16, 2024 · A new shock tube facility has been designed, constructed, and characterized at the University of Central Florida. This facility is capable of withstanding pressures of up to 1000 atm, allowing for combustion diagnostics of extreme conditions, such as in rocket combustion chambers or in novel power conversion cycles. WebFrom our computational experiments, it is found: (1) For shock tube experiment with less than a 15% endwall pressure increase, the conventional assumptions lead to reasonable accuracy in predicting stable species; (2) during reaction quenching, the consumption of radical species occurs efficiently and is nearly complete once the pressure drops to …
