Abstract The objective of this contribution is the development of a finite element model for finite rotation and large strain analysis of thin walled shells involving geometry intersections. The shell configuration is described by a linear polynomial in the thickness coordinate. The director of the shell is multiplicatively decomposed into a stretching parameter and an inextensible unit vector whose rotation is accomplished by an updated-rotation formulation. A rotation vector with three independent components is used throughout the shell which permits advantageously to consider smooth shells and compound shells by a unified procedure. This formulation is introduced into an isoparametric four-node element.… More >

Abstract Fully developed laminar mixed convection in inclined semicircular ducts is investigated numerically for the specific case of uniform heat input along the axial direction and uniform peripheral wall temperature, H1. The duct is considered over a variety of orientations (rotations) of its cross section, ranging from 0° (flat wall horizontally facing upward) to 180° (flat wall horizontally facing downward) with increment of 45° and a fixed inclination of its axis (with respect to the direction of gravity). In particular, the following conditions are considered: inclination α = 20°, 300 ≤ Re ≤ 1000, Pr = 4 and Gr = 1… More >
