The Secondary Flow around an Oscillating Circular Cylinder in a Uniform Flow

Journal of the Physical Society of Japan, 1999
Summary: The secondary flow around an oscillating circular cylinder in a uniform flow is investigated with the successive approximation of Navier-Stokes equations for low Reynolds numbers. The approximation is based on the Oseen's equations, and the equations and solution are expanded in power series in Reynolds number.

Secondary Flow in Rotating Bends

Journal of Engineering for Power, 1978
An equation describing the development of streamwise vorticity is derived. The fluid is assumed inviscid and incompressible and to have a gradient of rotating total pressure across the streamtube. The equation is used to calculate, by finite difference techniques, the streamwise vorticity development for bends, rotating straight pipes, rotating axial ...

Flow Visualization Study of Secondary Flow in a Corner.

1979
Abstract : An experimental investigation has been made of secondary flow in a 90 degree corner. The tests were run in a water tunnel at low speed (approximately 0.3 ft. per sec.) with emphasis on an attempt to visualize the embedded vortices in the laminar flow. The Reynolds number range was 11,000 to 52,500 per foot; the corner model was 9.75 in. wide

Secondary Flow in Noncircular Conduits

Journal of the Hydraulics Division, 1978
A requirement for calculating an accurate velocity distribution in noncircular conduits is a knowledge of the secondary flow distribution in these conduits. The cause of these secondary flows is considered in this paper and a simple momentum transfer model for Reynolds stresses is used to effect a solution for the secondary flow in a square duct.
