Performance Prediction and Experiment Study on Axial Pump Station Device

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...

Effects of Cone-Shaped Bend Inlet Cannulas of an Axial Blood Pump on Thrombus Formation: An Experiment and Simulation Study

BACKGROUND Cannula shape and connection style influence the risk of thrombus formation in the blood pump by varying the blood flow characteristics inside the pump. Inlet cannulas should be designed based on the need for anatomical fit and reducing the risk of thrombus generation in the blood pump. The effects on thrombus formation of the cone-shaped bend inlet cannulas of axial blood pumps shou...

Parametric study on axial compressor performance in design condition

In This paper, a parametric study of compressor performances was performed by streamline curvature method (SLC). Effects of three input parameters in design process, e.g., number of blades, distribution of blade thickness, and blade sweep angels, on the main objective parameters in aerodynamic design, e.g., velocity distribution, efficiency and pressure ratio, has been investigated in the param...

A method of performance estimation for axial-flow turbines based on losses prediction

The main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. The calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. In this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. Finally, the analysis an...
