... pulsatile flow turbines There are many applications where the high pressure turbine in a propulsion system is exposed to unsteady inflow conditions. Two common examples are turbines downstream of a pulse detonation combustor (PDC) and a turbocharger downstream of a reciprocating engine. In both...
