Numerical Analysis of Blade Geometry Generation Techniques for Centrifugal Compressors

Review of Variable Geometry Techniques Applied to Enhance the Performance of Centrifugal Compressors

Most centrifugal compressors are required to operate over a broad range of flow rates and to provide a high pressure ratio with high efficiency. In order to meet these demands the application of variable geometry techniques is often considered and applied. The potential areas for the application of variable geometry procedures lie at inlet to and discharge from the impeller. This paper reviews ...

A Cfd Analysis of Centrifugal Pump to Improve Discharge by Varying Blade Geometry

Centrifugal pumps are used in cooling the engine by pumping water as coolant into the engine. The normal function of the coolant is to discharge coolant at a specific velocity into the engine coolant volume, once the coolant crosses 150 C temperatures then it is taken to the radiator for cooling to 50 C. Due to changes in the engine design it is desired to have changes in the centrifugal pump d...

Thermoplastic Labyrinth Seals for Centrifugal Compressors

For over 15 years now, the efficiency and reliability of centrifugal compressors have been enhanced by the application of thermoplastic materials to the eye, shaft, and balance piston labyrinth seals. Traditionally these seals have been manufactured from metallic materials and have required relatively large clearances for reliability reasons. By upgrading to carefully selected engineered thermo...

A Comparison of Regenerative and Centrifugal Compressors

An Artificial Neural Network Model for Prediction of the Operational Parameters of Centrifugal Compressors: An Alternative Comparison Method for Regression

Nowadays, centrifugal compressors are commonly used in the oil and gas industry, particularly in the energy transmission facilities just like a gas pipeline stations. Therefore, these machines with different operational circumstances and thermodynamic characteristics are to be exploited according to the operational necessities. Generally, the most important operational parameters of a gas pipel...
