Abstract:
A rotating mass of fluid is known as vortex and the motion of the rotating mass of
fluid is known as vortex motion. Vorticity is the circulation per unit area. In this research
simulation of a vortex chamber is to be carried out in ANSYS CFD taking water as fluid domain
for generating a water vortex that is capable enough to move a turbine for electricity generation.
The CAD modelling of the setup was set down and simulation was done in fine mesh by taking
suitable wall function in the model of a cylindrical chamber along with a rectangular channel
with a contraction portion at the end of it where good amount of vortex generation was acquired
by observing velocity and pressure by setting different parameters. The results shows the pressure
and velocity contours with 3D velocity streamline flow and the curve of the velocity and pressure
curve shows the decrease of pressure and increase of velocity from inlet to outlet that leads to a
decent vortex generation.
