Abstract
Numerical study on a laminar and turbulent fluid flow and
temperature distribution in a rectangular duct with six types of vortex
generators has been carried out. A modified version of ESCEAT threedimension
code has been used to solve Navier-Stokes and energy equations.
The effect of vortex generator type, geometrical configuration, and
dimensions on flow and temperature in different planes has been presented.
The purpose of the present investigation is to highlight the complex threedimensional
interaction of the vortices generated by wings and other vortex
generators to understand how such vortices configurations structure the
velocity and temperature fields. Experiment in terms of velocities and
temperatures vectors and contours were performed on 6 configurations,
which experiments are (fin, fence, rib, wing-type, rectangular-type, and
winglet-type) vortex generators The results show good agreement with
published data.
