Vortex structure-based analysis of laminar flow behaviour and thermal characteristics in curved ducts
TL;DR: In this paper, the authors presented a numerical investigation for examining the secondary vortex motion and associated heat transfer process in fluid flow through curved passages and developed two numerical approaches offering improved capabilities for capturing the onset of hydrodynamic instability and resulting Dean vortices.
Journal ArticleDOI
Second law analysis of curved rectangular channels
TL;DR: In this article, the authors investigated the thermodynamic performance of the curved rectangular channels in laminar flow in terms of entropy generation and showed that the geometric parameters have important influences on the heat transfer performance of channel flows.

An analytical solution for Dean flow in curved ducts with rectangular cross section
Mahmood Norouzi,Nazanin Biglari +1 more
TL;DR: In this paper, a full analytical solution for incompressible flow inside the curved ducts with rectangular cross-section is presented for the first time, where the perturbation method is applied to solve the governing equations and curvature ratio is considered as the perturbing parameter.

Deterministic nonperiodic flow
TL;DR: In this paper, it was shown that nonperiodic solutions are ordinarily unstable with respect to small modifications, so that slightly differing initial states can evolve into considerably different states, and systems with bounded solutions are shown to possess bounded numerical solutions.

A bifurcation study of laminar flow in a curved tube of rectangular cross- section
TL;DR: In this paper, it was shown that for a square cross-section, the transition is a result of a complex structure of multiple, symmetric and asymmetric solutions, which is revealed by solving extended systems of equations for steady-state, fully developed, laminar flow, in a finite-element approximation, to locate exactly the positions of singular points.
