“…All these devices are described in detail in scientific literature. Finally, the use of a liquid film on the surface of a body reduces its frictional resistance [5]. In this study, drag reduction is achieved by changing the shape of a flat plate in laminar flow regime.…”

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.
