... jets pulsatile flow Cooling in gas turbines is achieved through internal cooling passages fed by compressor air with heat transfer enhancements such as turbulators, pin fins, and others. The most relied upon type of cooling in the hot section of the turbine is film cooling. In film cooling...

... 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...

... to the increasing use of variable geometry turbochargers (VGTs) that aim to improve turbocharger-response as well as to reduce emissions. The question of whether the unsteady concepts that apply to a nozzleless turbine are similar to a nozzled turbine remains yet to be answered. nozzles pulsatile flow...
