Project: Design Optimization of Centrifugal Pump by Fluid Mechanics

This project selection report, submitted by Dipesh Patel for a Master of Technology in Mechanical Engineering, focuses on the design optimization of centrifugal pumps using fluid mechanics principles and computational fluid dynamics (CFD) analysis. The project aims to enhance pump efficiency, particularly for applications in water supply and irrigation, addressing challenges posed by global warming and drought. The study proposes improvements by modifying impeller design parameters, such as outlet width, diameter, blade height, outlet angle, and blade number. The report highlights the scientific worth of the project, the alignment of the student's skills and knowledge, and the potential for future research in areas like sewage treatment. The project involves the use of various software tools and the application of data analysis skills. The report also includes a detailed annotated bibliography of relevant sources, covering topics such as centrifugal pump design, fluid flow, thermal design, and optimization techniques. The student plans to dedicate 18-24 hours per week to complete the project, demonstrating a strong motivation to contribute to solving global water scarcity challenges.

FLUID MECHANICS 2
Design Optimization of Centrifugal pump by fluid mechanics
Centrifugal pumps have been widely used for a long time for water supply plants, irrigation,
steam power plants, chemical plants, oil refineries, mines, food processing and hydraulic
power services due to their suitability in practically of any service. Many Africa and Arabian
countries are facing great challenges of drought due to the global warming effect. Hence it is
very important to find out the working conditions and design parameters that deliver ideal
output and greatest efficiency with the minimal power consumption to ensure that better
centrifugal pumps have been developed. To aid in the irrigation and water supply. Many of
the projects which have been initiated by their governments and other international
Humanitarian organisation have significantly failed due to the high cost of running the
projects
In the recent past, the application of computational fluid dynamics analysis has dramatically
gained grounds in the design of the centrifugal pumps. With the help of the computational
fluid mechanics approach, the internal flow of fluids in the pump impellers can, therefore, be
easily predicted. The centrifugal pumps are known to deliver essential energy to the fluid
which is to be pumped greatly through the velocity changes which occurs in the centrifugal
pump. Which entails the conversion of the mechanical energy to the hydraulic energy of the
handling fluid needed to get the fluid to the required height or place by the impeller blade or
centrifugal force. The input energy of the hydraulic pump is mechanical such as a mechanical
motor or a small engine, but the output energy is the hydraulic energy of the fluid which is
being raised. The previous modifications which have been done to the centrifugal pump have
yielded very little regarding improving the efficiency of the centrifugal pumps. I propose that
the performance of the centrifugal pumps can be improved by decreasing the impeller outlet
width, increasing the impeller outlet diameter, increase the impeller outlet blades height,
increase the impeller blade outlet angle and increase the number of blades on the impeller. In

this project, I want to come up with the ways through which the design of the centrifugal
pump can be optimized to achieve high efficiency by use of computational fluid mechanics
and other computer soft wares.
Is the project scientifically worth doing?
 This project will involve the design optimization of the centrifugal pump by use of
computational fluid mechanics analysis. It will enable me to develop the skills of
computational analysis and also on how to use different software in optimizing the
performance of rotary machines.
 This project proposes ways through which the efficiency of the centrifugal pump can be
improved to obtain the maximum output while using minimizing energy consumption.
The Design of the centrifugal pump can be optimized to come up with ways through
which the performance of the centrifugal pump can be enhanced.
 The proposals on how the optimized centrifugal pump can be used incorporated in the
irrigation and water supply projects to solve the problem food shortages in many parts of
the world.
How are your skills and knowledge base matched with the project?

computational analysis of the fluid mechanics and enable me to come up with way on
how to improve the performance of the centrifugal pump.
