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.
