THE ISOGEOMETRIC VARIATIONAL MULTISCALE METHOD FOR LAMINAR INCOMPRESSIBLE FLOW

Abstract

We present an application of the variational multiscale methodology to the com- putation of concentric annular pipe flow. Isogeometric analysis is utilized for higher order ap- proximation of the solution using Non-Uniform Rational B-Splines (NURBS) functions. The ability of NURBS to exactly represent curved geometries makes NURBS- based isogeometric analysis attractive for the application to the flow through the curved channel.
