Numerical and Economic Study of Performance of Centrifugal Pump as Turbine
In this paper, performance of centrifugal pump as turbine (PAT) is investigated numerically. Three different specific speeds are considered and three pumps are designed using diagrams from catalogues and CFturbo V.9 software. Next, models are analyzed by Ansys CFX 16 software and results are compared with those of CFturbo software. Also, a mesh study analysis for one case is performed in order ...
متن کاملImpeller and volute design and optimization of the centrifugal pump with low specific speed in order to extract performance curves
Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
متن کاملReview of Pump as Turbine (PAT) for Micro-Hydropower
Micro-hydropower projects are the excellent alternative for electricity generation in remote areas. These projects can be installed on small streams, rivers, and channels without any recognizable effect on environment. The only problem in micro-hydro projects is the high cost of turbine, for which Pump as Turbine (PAT) is a successful solution. An objective of the present study is to review the...
متن کاملDevelopment in Performance of Impeller used in Centrifugal Pump by using Computational Fluid Dynamics
The increased popularity of centrifugal pumps is due to largely to the comparatively recent development of high speed electric motors, steam turbines and internal combustion engines.To improve the performance of centrifugal pumps by studying the key components like impeller to find the optimum conditions using software. A literature review and lots of development in Computational CFD motivated ...
متن کاملEvaluation of floating impeller phenomena in a gyro centrifugal pump.
The Gyro centrifugal pump, developed as a totally implantable artificial heart, was designed with a free impeller in which the rotational shaft (male bearing) of the impeller was completely separated from the female bearing. For this type of pump, it is very important to keep the proper magnet balance (impeller-magnet and actuator-magnet balance) to prevent thrombus formation or bearing wear. W...
