    • Numerical investigation of detonation propagation through small orifice holes 

      Vashishtha, Ashish; Callaghan, Dean; Nolan, Cathal; Deiterding, Ralf (Sciendo, 2021)
      Seeking to better understand the physical phenomena underlying detonation wave propagation through small holes (especially the phenomenon of detonation re-initiation or its failure), we investigated the propagation of a ...
    • Oblique Detonation Wave Control with O3 and H2O2 Sensitization in Hypersonic Flow 

      Vashishtha, Ashish; Panigrahy, Snehasish; Campi, Dino; Callaghan, Dean; Nolan, Cathal; Deiterding, Ralf (MDPI journals, 2022-06-04)
      This numerical study investigates the effects of adding a small amount of ignition promoters for controlling the wedge-induced oblique shock wave (OSW) to oblique detonation wave (ODW) transition in a premixed hydrogen–air ...
    • Study of direct gas injection into stagnation zone of blunt nose at hypersonic flow 

      Harmon, Peter; Vashishtha, Ashish; Callaghan, Dean; Nolan, Cathal; Deiterding, Ralf (American Institute of Aeronautics and Astronautics, 2021-07-28)
      Direct gas injection in the shocked or compressed region has importance in many applications from drag control to ignition and pressure gain combustion. This numerical study is focused on direct light gas injection into ...
