Development And Performance Analysis Of Forced Vortex Apparatus
ABSTRACT
Vortices
are the major component of turbulent flow; the phenomenon is ubiquitous. The
quest to study the phenomenon however is being limited by the lack of
laboratory equipment to enhance the study. Vortex apparatus enables students
and researchers to produce both free and forced vortices and measure the vortex
surface profile. Studying natural phenomena such as hurricanes, tornadoes, and
whirlpools (free vortices) requires a full understanding of vortex behaviour.
The vortex apparatus when manufactured locally will ensure that it is readily
available in a most Nigerian university, hence promoting the knowledge and
application of vortex and vortex shedding. The apparatus consists of the
Hydraulic bench, cylinder vessels, valves, pipes, push-in orifice, impeller,
and electric pump. While the material used was water source able from around
the environment.
