Abstract
The process, particularly useful in blood oxygenators, whereby a differential velocity between a fluid and a diffusing surface of hollow tubes by a rotating member such that the boundary layer is perturbed enhancing the coefficient of mass and thermal transfer. The differential velocity is achieved by rotating hollow tubes containing one fluid in a second fluid, or by apposing a rotating member to the surface of the stationary hollow tubes.
