|Title:||Modeling fully developed laminar flow in a helical duct with rectangular cross section and finite pitch|
|Abstract:||The mass and momentum transport equations are written in an orthogonal coordinate system using Germano's transformation to model a laminar flow in a helical duct with a rectangular cross section and finite pitch. The system of governing equations are discretized and solved by the finite-volume numerical method. The three dimensional domain is reduced to a two dimensional slab of cells. orthogonal to the main flow direction, enforcing the fully developed state for 2 pi/(tau.d(h)) >> 1 where tau and d(h) representing the duct's center-line torsion and its hydraulic diameter. This approximation and the use of an orthogonal grid allow a great simplification on the numerical procedure. Comparisons of the numerical solution against experimental data are drawn to assess the accuracy of the approximation. Crown Copyright (C) 2011 Published by Elsevier Inc. All rights reserved.|
