Katabatic flows along a planar slope in a viscous stably-stratified fluid are investigated analytically and numerically, with an emphasis on flow features arising from the action of the Coriolis force. Two idealized flow types are considered: turbulent flow along a uniformly cooled slope, and two-dimensional laminar flow induced by a cold strip of finite width running down the slope. In the cas...

Finite element analysis (FEA) and continuum mechanics techniques have been used to model the thermal residual stress distribution in bonded joints and assess the suitability of using two-dimensional (2D) analysis methods. The methods are first employed to investigate stresses in metal-epoxy bi-material strip samples. The change in curvature of two bi-material strip systems during heating and co...

In order to get a more safety and economic foundation, finite element method was performed for piled mat cap strip by the software of STAAD. Through analysis, plate distribution region bending moment shear stress were researched; meanwhile, considering compatibility deformation plate, how chose design value researched. The result showed that: single is not representative, average 9 plates (3x3 ...

In two-dimensional topological insulators, such as inverted HgTe/CdTe quantum wells, helical quantum spin Hall (QSH) states persist even at finite magnetic fields below a critical magnetic field Bc, above which only quantum Hall (QH) states can be found. Using linear-response theory, we theoretically investigate the magnetooptical properties of inverted HgTe/CdTe quantum wells, both for infinit...

The finite-strip method (FSM) is a hybrid technique which combines spectral and finite-element methods. Finite-element approximations are made for each mode of a finite Fourier series expansion. The Galerkin formulated method is set apart from other weighted-residual techniques by the selection of two types of basis functions, a piecewise linear interpolating function and a trigonometric functi...

This paper addresses the need to know the unsteady forces and moments on an underwater vehicle in finite depth water, at small enough submergences for it to be influenced by sea waves. The forces are those due to the waves themselves as well as the radiation forces due to unsteady vehicle motions. Knowledge of these forces and the mass distribution of the vehicle allow solution of the equations...

Numerical simulations of the incompressible Euler equations are performed using the Taylor-Green vortex initial conditions and resolutions up to 4096^{3}. The results are analyzed in terms of the classical analyticity-strip method and Beale, Kato, and Majda (BKM) theorem. A well-resolved acceleration of the time decay of the width of the analyticity strip δ(t) is observed at the highest resolut...

Interest in the seakeeping loads of vessels has increased dramatically in recent years. In current design practice, methods for predicting seakeeping motions and loads are mainly in two categories, strip theory methods and 3Dpanel methods. Methods based on strip theory provide reasonable motion prediction and are computationally efficient. However, many strip theory methods provide only hull gi...
