RISCurvilinear Coordinates and Physical Components: An Application to the Problem of Viscous Flow and Heat Transfer in Smoothly Curved Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Expressions are derived for the gradient, divergence, Laplacian, curl, and material time derivative in terms of general curvilinear coordinates using physical components of all vector quantities. ...
The Effect of Torsion on the Bifurcation Structure of Laminar Flow in a Helical Square Duct
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laminar fully developed flow problem in a helical square duct with a finite pitch is solved numerically using the finite-volume method with the SIMPLEC algorithm. h2 -extrapolation is used ...
