Reducing drag on a flat plate subjected to incompressible laminar flow

Abstract

The idea behind this work comes from the question: What is the impact of plate corrugations on drag? In this context, a numerical study of laminar incompressible flow over a flat plate and over corrugated plates is carried out. Numerical analysis is performed for low Reynolds numbers (Re= 10, Re = 50, Re = 100, Re = 500, Re =1000) using the computational fluid dynamics (CFD) software ANSYS FLUENT. Simulations results are compared to each others and with those of the reference plate (flat plate (figure 4a)). Comparisons are made via drag coefficient C d . This work is the beginning of a study that evaluates the impact of corrugations on drag reduction on a flat plate.

Numerical study of new techniques drag reduction: application to aerodynamic devices

“…We study the effect of corrugating the shape of a flat plate on the drag reduction in the case of laminar flows [15]. Numerical simulations on various shapes and orientations of the corrugations have been performed for low Reynolds numbers.…”
