Alternative approaches to rear end drag reduction

Introduction

Aerodynamic drag of a commercial vehicle is a large part of the vehicles fuel consumption,
according to Hucho it can contribute to as much as 60 % of the vehicles fuel consumption.
So far aerodynamic design of commercial vehicles has concentrated on the front end of the
vehicle. Since it produces most drag it has been the most urgent part to optimise. This
optimisation can easily be spotted on trucks and tourist coaches. The rear end confi ....etc

Drag Reduction in Ships Using Micro bubbles Technology Abstract: Drag is a mechanical force which is generated with a solid object that is moving through a fluid. There should be movement between the object and the fluid. Drag acts in opposite direction to the direction of motion of the body.

When a body is moving then it experiences a drag force and it usually has two components, frictional drag which is called viscous drag and pressure drag which is called form drag or profile drag.

Frictional drag is generated with friction between th ....etc

1. INTRODUCTION
Drag is a mechanical force generated by a solid object moving through a fluid. For drag to be generated, the solid body must be in contact with the fluid. If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag. Drag acts in the direction opposite to the direction of motion of the body.
A body moving through a fluid experiences a ....etc
