There is evidence that the application of porous media to the surfaces of bluff bodies
immersed in turbulent fluid flows has a profound effect on the associated aerodynamic …

This paper presents the study of the overall aerodynamic performance of road vehicles and
suggests a method to reduce the drag force and also to find the optimum location for placing …

In this study, we attempted a novel drag reduction technique for 25° and 35° Ahmed models
by experimenting with two types of flap structures, respectively, added to the slant edges of …

In this paper, a simple passive device is proposed for drag reduction on the 35° Ahmed
body. The device is a simple rectangular flap installed at the slant surface of the model to …

Aerodynamic drag reduction is considered to be one of the most effective ways to minimize
fuel consumption. Hence, this work focuses on reviewing some of the most promising …

The drag reduction performance of a half airfoil attached to a trailer and the roof fairing at
different positions was experimentally investigated in a wind tunnel. Half airfoils have NACA …

In fluid mechanics, drag related problems aim to reduce fuel consumption. This paper is
intended to provide guidance for drag reduction applications on cars. The review covers …

This research modifies the leading-edge structure of NACA 0015 and NACA 4415 to
resemble the nose of a beluga whale. The focus of this modification is to improve the airfoil's …
