Panel Discussion on Inducer Design Criteria

معیار های طراحی ایندیوسر

This article reports a panel discussion titled Inducer Design Criteria presented at the 9th International Symposium on Transport Phenomena and Dynamics of Rotating Machinery (ISROMAC-9). The presentations of the panelists and the subsequent discussions are summarized. It is shown that cavitation instabilities are major problems in modern turbopumps and that design criteria to eliminate them are needed. Available design methods for inducers and marine propellers are reviewed, and new criteria to enhance stability are proposed. The current status of CFD is reviewed and an example of successful application is shown. Discussions of several specific topics are reported and future research needs are noted.

Design and CFD Analysis of Centrifugal Pump

Design and CFD Analysis of Centrifugal Pump

Abstract— the purpose of this paper is to identify /observe and determine the pattern of velocity profile and pressure distribution by using CFD simulation program after the 3D design and modeling of the pump is made using Vista CPD. Basically, this paper revolves around the idea of investigating the effect and distribution of velocity profile and pressure within a pump having the following specification, Head = 20 m, Flow rate = 280 m3/hr, and RPM = 1450. 3D Navier–Stokes equations were solved using ANSYS CFX.

The standard k -e turbulence model was chosen for turbulence model. From the simulation results it was observed that the pressure increases gradually from impeller inlet to outlet. The static pressure on pressure side is evidently larger than that on suction side at the same impeller radius. In addition to this, it was observed that, the velocity increases from impeller inlet until it enters the volute casing. It then drops to a minimum value at outlet region.

CFD Simulation of Centrifugal Pump Impeller Using ANSYS-CFX

CFD Simulation of Centrifugal Pump Impeller Using 

ANSYS-CFX

ABSTRACT: Centrifugal pumps are a most commonly used in different fields like industries, agriculture and domestic applications. Computational Fluid Dynamics is most commonly used tool for simulation and analysis. 3-D numerical CFD tool is used for simulation of the flow field characteristics inside the turbo machinery. CFD simulation makes it possible to visualize the flow condition inside centrifugal pump. The present paper describes the head, power, efficiency and to evaluate the pump performance using the ANSYS CFX-14, a computational fluid dynamics simulation tool. These simulations of centrifugal pumps are strongly related to cavitation flow phenomena, which may occur in either the rotating runner-impeller or the stationary parts of the centrifugal pumps. The numerical simulation can be used to detect the cavitation in centrifugal pump and to get safe range of operating at different flow rate and rotating speed.

KEYWORDS: Centrifugal pump impeller, CFD, Head, Power, Efficiency, Cavitation.
