This paper develops schematics and evaluates the performance of hybrid mesh turbomachinery at patenting stage individual technical solutions. type turbomachine uses reduced-sized blades also forms flow channels with a structure between blades. The research methods are based on simulations using computational fluid dynamics (CFD) additive technologies. An intermediate conclusion is that new scie...

Abstract This paper explores the suitability of Artificial Neural Networks (ANNs) as an enabler Design Automation in turbomachinery industry. Specifically, provides 1) a preliminary estimation effectiveness ANNs to define values for design variables reciprocating compressors (RC) and 2) comparison performance with traditional more computationally demanding methods like CFD. A tailored ANN train...

Abstract In this paper, we (i) present a methodology for determining the aerodynamic performance of bi-directional turbomachines pumped thermal energy storage, i.e., designed to operate as compressor in one direction, and then turbine opposite (ii) carry out computations such turbomachines, (iii) propose principles conceptual design these devices. Focus is placed on using storage cycle not only...

The designers of radial turbomachinery need detailed information on the impact side chamber flow axial thrust and torque. A previous paper investigated centripetal through narrow rotor–stator cavities compared thrust, rotor torque pressure distribution to case without through-flow. Consequently, this extends range centrifugal through-flow as it may occur in hub turbomachinery. chosen operating ...

Imagine yourself looking out the window on a commercial flight at the aircraft engine outside. For four years, I worked at Honeywell Aerospace as product design engineer in a research team investigating flutter and forced response issues in turbomachinery for aircraft engines. Flutter is an aeroelastic issue that can cause near-instantaneous and catastrophic part failure. It results from the un...

The He Brayton cycle appears to be the best nearterm power conversion method for maximizing the economic potential of fusion. Key factors affecting the Brayton cycle efficiency includes the turbine inlet temperature, compressor and turbine adiabatic efficiencies, recuperator effectiveness and cycle fractional pressure loss. The compression ratio is also important because for fusion conditions, ...

New methods are presented that allow straightforward application of complex nonlinearities to finite element based rotor dynamic analyses. The key features are 1) the methods can be implemented with existing finite element or dynamic simulation programs, 2) formulation is general for simple application to a wide range of problems, and 3) implementation is simplified because nonlinear aspects ar...
