APPLICATION OF TESLA VALVE FOR MITIGATING
WATER HAMMER IN PIPE SYSTEM

ABSTRACT

RESEARCH BACKGROUND
The water hammer effect happens when the check valve stops water flow in a pipe
system, which creates high-pressure flow to the check valve. It will damage the check
valve and shorten its lifespan, sometimes accidents may happen. In order to increase
safety and cost efficiency, Tesla Valve can be applied to a pipe system. Tesla Valve is
a special structure, which decreases pressure travelling through high speed, without
any moving part. Installing it in front of the check valve can reduce the water hammer
effect by reducing the velocity of fluid flow.

METHODOLOGY
Data Collection from Simulation: BEng (Hons) in Civil Engineering
Use Fluid software to simulate and analyze water travel through Tesla Valve. It should Department of Construction,
show in the image how fluid travels, and data of fluid flow rate. Environment and Engineering

FINDINGS
Through simulation done by Ansys software, the Tesla valve with a water drop shape in
the middle, is the most effective sample to decrease the velocity of fluid flow. However, OBJECTIVES
given the hilly terrain of Hong Kong, the water pressure of our water supply networks
generally ranges from 60 to 80 meters, in which one stage of the Tesla valve is unable The objectives of the project are:
to decrease fluid flow to a safer velocity. A number of stages of the Tesla Valve are • Putting Tesla value into pipe system
needed to increase the lifespan of the check valve. However, due to the limitations, to reduce the effect of water hammer
the outcome of this research is unable to determine the number of stages required to
optimize the Tesla Valve needed to reduce the water hammer effect. • Increase the lifespan of the valve

ABOUT THE INVESTIGATOR

My name is James. I loved making models since I was a kid, and this hobby encouraged
me to become a civil engineer. I hope I can use my knowledge to improve others' living
quality. I want to thank my FYP supervisor Dr. Keane Yaohui LIU for helping me
complete my project.
