Slipstream (computing), Slipstream
A slipstream is a region behind a moving object in which a Wake (physics), wake of fluid (typically air or water) is moving at velocities comparable to that of the moving object, relative to the ambient fluid through which the object is moving. The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it. "Slipstreaming" or "drafting (aerodynamics), drafting" works because of the relative motion of the fluid in the slipstream. Overview A slipstream created by turbulent flow has a slightly lower pressure than the ambient fluid around the object. When the flow is laminar flow, laminar, the pressure behind the object is higher than the surrounding fluid. The shape of an object determines how strong the effect is. In general, the more aerodynamic an object is, the smaller and weaker its slipstream will be. For example, a box-like front (relative to the object's motion) will collide with the medium's particles at a high rate, transferring ...
