Formularization of Characteristic Curves of Axial-flow Blowers

Flow Field Interference Characteristic of Axial Ring Wing Configuration

Article history: Received: 25.10.2014. Received in revised form: 19.03.2014. Accepted: 20.03.2014. To analyze the air flow interference between upper and lower wings in axial ring wing configuration, NASA SC(2)-1006 supercritical airfoil is chosen as the basic airfoil. Flow field around the doublewing structure with different relative distances between upper and lower wings is numerically simul...

Performance Prediction Modeling of Axial-Flow Compressor by Flow Equations

Design models of multi- stage, axial flow compressor are developed for gas turbine engines. Axial flow compressor is one of the most important parts of gas turbine units. Therefore, its design and performance prediction are very important. One-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. In this appro...

Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields

• M , the equivalent of a single time step, if we explore the curves for a given (t, τ). Examples of this are shown using LIC images throughout the paper, for example Figures 7d and 7e. Furthermore, this case applies to advected stream surfaces for a given (t, τ) such as the one shown in Figure 9. It shall be noted that the pre-computed ̄̄ q can be used to compute all advected stream surfaces for...

Regression Error Characteristic Curves

Receiver Operating Characteristic (ROC) curves provide a powerful tool for visualizing and comparing classification results. Regression Error Characteristic (REC) curves generalize ROC curves to regression. REC curves plot the error tolerance on the xaxis versus the percentage of points predicted within the tolerance on the y-axis. The resulting curve estimates the cumulative distribution funct...
