Abstract: Pressure gain combustion (PGC) shows potential to increase the cycle efficiency of conventional gas turbine engines (GTEs) if used in place of the steady combustor. However, a turbine driven by pulsing flow experiences a ...

Abstract: Multiple highfidelity timeaccurate computational fluid dynamics simulations were performed to investigate the effects of upstream stator loading and rotor shock strength on vortex shedding characteristics in a singlestage ...

Abstract: Turbomachines are an integral part of society, with global trends demanding more efficient designs while staying within structural limits. Fan blade designs must be designed for both steady and vibratory structural responses. ...

Abstract: This paper describes the application of reducedorder modeling techniques in the simulation of conjugate heat transfer processes. In a reducedorder model (ROM), the dominate features of a system are represented using a ...

Abstract: Inducers are used as a first stage in pumps to minimize cavitation and allow the pump to operate at lower inlet head conditions. Inlet flow recirculation or backflow in the inducer occurs at low flow conditions and can ...

Abstract: Design space exploration (DSE) is the process whereby a designer seeks to understand some results across a set of design variations. Structural DSE of turbomachinery compressor blades is often challenging because the large ...

Abstract: There is widespread interest in using pressure gain combustion in gas turbine engines to increase gas turbine engine efficiency and reduce fuel consumption. However, the fluctuating turbine inlet conditions inherent with ...
