A Hybrid Vortex Solution for Radial Equilibrium in Axial Compressors
<p>A hybrid vortex solution using the radial equilibrium equation for three dimensional design in axial compressors is generated. One of the most common used vortex solutions is Free Vortex. However, it ignores the fact that axial velocity varies with radius. The Hybrid Vortex includes axial …

Determination of a Simplified High-Order Vortex Equation for Radial Equilibrium with CFD Verification
… model combines the well-established simple radial equilibrium vortex models into a higher order equation that will establish the basis for a more flow-accurate model. In this paper, we will discuss the basis and derivation of these vortex models, the shortcomings of current techniques, and …

The Numerical solution of the radial-equilibrium equation for swirling flow in arbitrarily shaped ducts
The radial-equilibrium equation is discussed with regard to turbomachinery. The complete equation is derived for nonviscous flow and the simplifications are indicated. Five different techniques for the solution of three-dimensional compressible flow in a duct are examined in detail. A comparison …

Pressure distribution on a rotating axial-flow compressor blade
… distributions on the rotor blade using simple radial equilibrium, boundary layer theory and an existing finite-difference, blade-to-blade computer program is presented. A comparison of the experimental and theoretical pressure distribution on the rotor blade at 25 percent, 50 percent and 75 …

A Hybrid Vortex Solution for Surge Margin Enhancement in Axial Compressors
<p>A new vortex solution to the Simple Radial Equilibrium Equation (SREE) is presented that incorporates endwall effects into the preliminary design stage of a single stage, low pressure compressor with a hub-to-tip ratio of 0.4 and non-axial inlet flow. This vortex solution is proposed to overcome …

Corrections to inter-blade-row flow measurements in axial compressors
… such as mass and energy conservation and radial equilibrium. The corrected data have shown improved consistencies: the variation of the integrated mass flow values along the compressor axial locations was reduced from ±15% to ±4% from the inlet value, and the static pressure distribution …

An engine air-brake integration study
… low pressure in the vortex core from simple radial equilibrium, thereby generating pressure drag. The 4-BB internal plug and 5-BB external plug nozzles of BPR 8 are chosen to provide a realistic environment for model-scale tests at the NASA Aero-Acoustic Propulsion Lab (AAPL). The objectives …
