    • Investigation of a modified circular nozzle for cold spray applications 

      Sharma, Amit Kumar; Vashishtha, Ashish; Callaghan, Dean; Bakshi, Srinivasan Rao; Kamaraj, M.; Raghavendra, Ramesh (ASM International, 2023-05-22)
      The current work numerically evaluates the efficacy of a coflowing nozzle for cold spray applications with the aim to mitigate nozzle clogging by reducing the length of its divergent section. The high-pressure nitrogen ...

    • Mach number dependence of flow instability around a spiked body 

      Vashishtha, Ashish; Khurana, Shashank (AIP Publishing, 2023-05-05)
      A forward-facing aerospike have been identified as a passive flow control device for enhancing the aerodynamic efficiency and reducing the heat transfer in high-speed flows. In addition, it has been reported that the ...

    • Numerical study of oblique detonation wave control for fuel blends 

      Kore, Rushikesh; Vashishtha, Ashish (2023)
      The current study is motivated to develop control strategies for oblique detonation wave formation on a finite length wedge in a premixed methane-air mixture. The effectiveness of hydrogen blends (0 - 100%) to methaneair ...

    • Unsteady DSMC Simulation of blunt nose with spike at hypersonic rarefield flows 

      Ravuri, Nishita; Scully, Stephen; Vashishtha, Ashish (2023-03-29)
      To design an efficient ram-air intake for an air-breathing propulsion system for VLEO (Very-Low) / SLEO (Super Low) Earth Orbit satellites requires consideration of the unsteady effects in the hypersonic low-density or ...
