ABSTRACT:
A method and apparatus for reducing the amount of an external fluid which travels through an opening into an enclosed area. Also, a method and apparatus for protecting a surface area or plane from contact with or intermixing with an external fluid. The method, in general, comprises causing a fluid to flow, in laminar form, in proximity to or directly across an opening, a surface or an area plane to be protected. The depth or thickness of the flowing laminar fluid layer at its source of origin is at least about 0.05 times the distance across the opening, surface area or plane to be protected, in the principal direction of flow of the fluid at its source of origin. The width of fluid flow at its source of origin and transverse the direction of fluid flow is at least about as great as the maximum width of the opening, surface or area plane to be protected, transverse the direction of fluid flow. The Force Number of the fluid must range between about 0.05 and about 50; the preferred range for the Force Number is from about 0.1 to about 10.
