Use of transpiration for reduction of resistance to relative movement of parallel plates
Longyin Jiao, J. M. Floryan
Abstract
A study of surface transpiration demonstrates its use for reduction of forces required to maintain the relative movement of parallel plates. Competition between reduction of the effective spacing between the plates, elimination of the direct contact between the transpired wall and the bulk of the fluid, and generation of a driving force through the nonlinear streaming leads to a wide range of responses, including resistance reduction. It is argued that transpiration can be used as an alternative propulsion method.
