Abstract EN
Three cylinder-based geometries were evaluated at five different rotating speeds (ω = 20.94, 62.83, 94.25, 125.66, and 157.08 rad·s−1) to obtain the fluid flow pattern in nonsteady conditions.
Two of the models were modified at the lower region, also known as tip section, by means of inverted and right truncated cone geometries, respectively.
The experimental technique used a visualization cell and a Particle Imaging Velocimetry installation to obtain the vector field at the central plane of the volume.
The Line Integral Convolution Method was used to obtain the fluid motion at the plane.
In addition, the scalar kinetic energy and the time series were calculated to perform the normal probability plot.
This procedure was used to determine the nonlinear fluid flow pattern.
It was also used to identify two different flow regimens in physical and numerical results.
As the rotation speed increased, the turbulent regions were placed together and moved.
The process makes experimental observation difficult.
The biphasic and turbulence constitutive equations were solved with the Computational Fluid Dynamics technique.
Numerical results were compared with physical experiments for validation.
The model with the inverted truncated cone tip presented better stability in the fluid flow pattern along the rotation speed range.
