Interested in the Fluid Dynamics of an Air Reverser?
In this paper a theoretical analysis of the fluid mechanics of the air cushion of the air reversers used in web-handling systems is presented. This paper includes :
- A two-dimensional model of the air flow derived by averaging the equations of conservation of mass and mommentum over the clearance between the web and the reverser.
- The resulting Euler equations are solved analytically for the one-dimensional case and mumberically for the two-dimensional case.
- Results are compared with an empirical formula and the one-dimensional air-jet theory developed for hovercraft.
- Conditions that maximize the air pressure supporting the web are analyzed and design guideline deduced.
