Using laminar flow (fully developed pipe flow) of a pipe to balance drag forces on a moving object such as a vehicle. Due to laminar flow formed through a pipe, uniform flow structure and increased central velocities would endure bending and travel towards the low pressure point of contact on the vehicle. Just like super critical flow, these air forces would stay 'bound' and disperse at the low pressures.

摘要

Abstract The purpose of this paper is to present ideas for minimising the drag forces on the rear of moving objects such as vehicles, planes, trains and trucks etc. This paper also presents the theory of which these ideas are based, basic findings from initial modelling and further formulas and ideas for modelling the theory at a higher detail. Ideas put forth in this paper were based on fluid dynamic principles. These principles included laminar flow of pipes and the fact that water undergoes natural changes of pressure through a pipe called laminar flow. Basically it is assumed that using a flow with extra velocities and a 'structured' design like that associated with laminar flow, will be drawn to the low pressures and 'interrupt' turbulent flow and in turn increase the air pressures at these locations. This in turn will lead to the reduction of drag forces.
