| 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. | ||
