A WAKE MODEL FOR FREE-STREAMLINE FLOW THEORY. PART I. FULLY AND PARTIALLY DEVELOPED WAKE FLOWS AND CAVITY FLOWS PAST AN OBLIQUE FLAT PLATE
Abstract
A wake model for the free-streamline theory is proposed to treat the two-dimensional flow past an obstacle with a wake or cavity formation. The flow is approximately described by an equivalent potential flow such that along the wake boundary the pressure first assumes a prescribed constant under-pressure in a region downstream of the separation points (called the near-wake) and then increases continuously from this underpressure to the given free stream value in an infinite wake strip of finite width (the farwake). The boundary trailing a lifting body is allowed to change its slope and curvature at finite distances from the body and is required to be parallel to the main stream only asymptotically at downstream infinity. The pressure varies so that the upper and lower boundaries of the far-wake form a branch slit of undetermined shape in the hodograph plane. (Author)
