Abstract
A rectangular cross section channel, with both a straight
and a curved portion, was designed and built to create the
laminar secondary Taylor-Goertler vortex flow. An aerosol
was used to visualize these flow patterns, and photographs
of the results are presented. A hot wire anemometer investigation
of one location in the curved section was conducted
to obtain the mean velocity profiles and turbulence levels.
The pressure drop along both the straight and the curved
sections was measured and compared. A constant temperature
wall heater was also designed and installed in the straight
section of the channel. Approximate values of the heating
losses were obtained and the overall and local heat transfer
coefficients were calculated for the straight portion of the
channel. It was concluded that the vortices develop with
both velocity increases and distance along the channel, and
that the increase in pressure drop due to the vortices
varied from near zero to approximately 20% with increasing
Reynolds numbers.
