Abstract: Derivation of the governing equations for compressible flow in a tapered annular seal is based on Hirs’ turbulent bulk-flow model. Zeroth and first-order perturbation equations are developed by ...

Abstract: In order to soften the effects of rub, the smooth stators of turbine gas seals are sometimes replaced by a honeycomb surface. This deliberately roughened stator and smooth rotor combination ...

Abstract: More than 40% of the more than 20,000 planners in the United States influence the manner in which water, sewer, drainage, streets, and other kinds of physical infrastructure are planned and used. But to what extent are ...
