Abstract Over the past two decades, there has been much development in discontinuous Galerkin methods for incompressible flows and compressible with a positive Mach number, but almost no attention paid to variable-density at low speeds. This paper presents pressure-based method flow low-Mach number limit. We use pressure correction method, which is simplified by solving mass flux instead of vel...

The interaction between mean flow and finite-amplitude disturbances in. certain experimentally observed unstable, compressible laminar wakes is considered theoretically without explicitly assuming small amplification rates. Boundary-layer form of the two-dimensional mean-flow momentum, kinetic energy and thermal energy equations and the time-averaged kinetic energy equation of spatially growing...

We analyze 2-dimensional chaotic forms resulting from very simple systems based on two chaotic characteristics that is rotation and parallel movement or translation in geometric terms. Re ection is another alternative, along with rotation, for several interesting chaotic formations. Rotation and translation are very common types of movements in the world around us. Chaotic or non-chaotic forms ...

We consider 3D steady flow of fresh water over a salt water body in a confined aquifer of constant thickness D, with application to a pumping well in a coastal aquifer. With neglect of mixing, a sharp interface separates the two fluid bodies and an existing analytical solution, based on the Dupuit assumption, is adopted. The aim is to solve for the mixing between the fresh and salt waters for a...

In the preceding issue of these PROCZEDINGS, the fact of characteristic frequencies for non-polar bonds was introduced into the Born-Karman heat capacity equations, which were then, with certain approximations, brought into a general simplified form for non-polar compounds.' With the aid of these simplified equations, the heat capacities of some organic solids will now be. calculated and compar...

ABSTRACT This paper presents the theoretical developments of two finite strip methods (i.e. semi-analytical and full-analytical) for the post-buckling analysis of isotropic plates. In the semi-analytical finite strip approach, all the displacements are postulated by the appropriate shape functions while in the development process of the full-analytical approach, the Von-Karman’s equilibrium equ...

in this paper, non-polynomial spline method for solving coupled burgers’ equations are presented. we take a new spline function. the stability analysis using von-neumann technique shows the scheme is unconditionally stable. to test accuracy the error norms2l, ∞l are computed and give two examples to illustrate the sufficiency of the method for solving such nonlinear partial differential equatio...

The investigation on the impacts of magnetic field, thermal radiation, generation heat and mass transfer in a porous-medium-embedded homogenous nanofluid flow between two stretchable spinning disks is crucial since are prevalent many engineering technological applications. objective this research was to analyze influences these parameters using Cattaneo-Christov flux model against flow’s temper...
