In this paper we present a C++ implementation of a numerical solver for the Euler equations about rotating geometries (Turbomachinery). This implementation represents a working prototype C++ solver which obtains performances comparable to a reference Fortran application. We obtain this performance by providing abstractions at the level of collections of objects , thus minimizing the introductio...

A supercritical CO2 (S-CO2) Brayton cycle is a compact and simple power conversion system with competitive efficiency. However, the strong real gas effects of S-CO2 pose challenges to design its components. In particular, designing turbomachinery for expansion compression processes has accurately reflect effects. Windage loss one major losses that affects motor load heat generation in turbomach...

Coherence based source analysis techniques can be used to identify the contribution of broadband noise sources in the exhaust of a gas turbine and hence enable the design of noise reduction devices. However, when the broadband noise source propagates in a non-linear fashion the identified contribution using ordinary coherence methods will be inaccurate. In this paper, an analysis technique to e...

This paper describes a newly developed streamline curvature throughflow method for the analysis of radial or mixed flow machines. The code includes curved walls, curved leading and trailing edges, and internal blade row calculating stations. A general method of specifying the empirical data provides separate treatment of blockage, losses, and deviation. Incompressible and compressible fluids ar...

Computational Fluid Dynamics is one of the most relied upon tools in design and analysis components turbomachines. From propulsion fan at inlet, through compressor combustion sections, to turbines outlet, CFD used perform fluid flow heat transfer analyses help designers extract highest performance out each component. In some cases, such as point axial compressor, current methods are capable del...

Current rotorcraft gas turbine engines typically use titanium alloys and steel for the compressor section single-crystal nickel superalloys hot-section stator vanes rotor blades. However, these material selections are rapidly changing due to increased requirements of power-density efficiency. Future U.S. Army will be using ceramic matrix composites many high temperature engine components their ...
