One-dimensional radiation-hydrodynamic simulations of imploding spherical plasma liners with detailed equation-of-state modeling [PDF]
Physics of Plasmas 19, 102701 (2012), 2012 This work extends the one-dimensional radiation-hydrodynamic imploding spherical argon plasma liner simulations of T. J. Awe et al. [Phys. Plasmas 18, 072705 (2011)] by using a detailed tabular equation-of-state (EOS) model, whereas Awe et al. used a polytropic EOS model.

Drag Control by Hydrogen Injection in Shocked Stagnation Zone of Blunt Nose [PDF]
IOP Conf. Ser.: Mater. Sci. Eng. 1024 (2021) 012110, 2020 The main motivation of the current study is to propose a high-pressure hydrogen injection as an hybrid active flow control technique in order to manipulate the flow-field in front of a blunt nose during hypersonic flight. Hydrogen injection can lead to self-igition under the right environment conditions in a stagnation zone, and may cause thermal heat ...

Impinging Performance of High-Pressure Water Jets Emitting from Different Nozzle Orifice Shapes
Geofluids, 2020 The impinging pressure of a water jet is a key factor in engineering applications, and the jet shape has a great influence on this pressure. In this paper, five different nozzle shapes were designed, and impacting tests were conducted based on a self ...

Ideal hydrodynamic scaling relations for a stagnated imploding spherical plasma liner formed by an array of merging plasma jets [PDF]
Physics of Plasmas 20, 032706 (2013), 2013 This work presents scaling relations for the peak thermal pressure and stagnation time (over which peak pressure is sustained) for an imploding spherical plasma liner formed by an array of merging plasma jets. Results were derived from three-dimensional (3D) ideal hydrodynamic simulation results obtained using the smoothed particle hydrodynamics code ...

Single cavitation bubble dynamics in a stagnation flow [PDF]
, 2023 Jetting of collapsing bubbles is a key aspect in cavitation-driven fluid-solid interactions as it shapes the bubble dynamics and additionally due to its direct interaction with the wall. We study experimentally and numerically the near-wall collapse and jetting of a single bubble seeded into the stagnation flow of a wall jet, i.e.

Design of Water Fire Extinguishing System for Protection of Metro Rolling Stock Stagnation Zones [PDF]
EPJ Web of Conferences, 2021 Metro rolling stock stagnation zones are quite long. This causes a number of difficulties in choosing and designing a water fire extinguishing system, as it directly affects the pressure loss in pipelines when water is supplied over such a long distance.
