In this article, the flow pattern of a fluid of grade four between two elliptic tubes is determined using elliptic coordinates, and a comparison between the position of the maximum of the axial velocity in the present case and in the case of two concentric circular tubes shows a basic difference.Abstract:
Using elliptic coordinates, the flow pattern of a fluid of grade four between two elliptic tubes is determined. A comparison between the position of the maximum of the axial velocity in the present case and in the case of two concentric circular tubes shows a basic difference. In the elliptic case the maximum is shifted towards the external wall, while in the case of concentric circular tubes the shift is in the direction of the internal wall. The secondary flow shows dissymmetry with reference to the intermediate line\(\tilde \psi _4 = 0\), which itself lies nearer to the external wall.read more

Slow viscous flow
TL;DR: The second edition of this book as mentioned in this paper is the most complete and complete version of the first edition of the paper, with a much richer coverage of theoretical hydrodynamics, including the second principle of thermodynamics, the Boussinesq approximation, time dependent flows, Marangoni convection, Kovasznay flow, plane periodic solutions, Hele-Shaw cells, Stokeslets, rotlets, finite element methods, Wannier flow, corner eddies, and analysis of the Stokes operator.
