Discretisation of the Hydrodynamic Transport equations using the Control Region Approximation
نویسندگان
چکیده
This paper focuses on the discretisation of the hydrodynamic transport equations for electrons in sub-micron MOSFET structures. In particular initialisation of the electron temperature equation, and the important problem of accurately calculating the energy input term f J E j on a generalised triangular FE mesh will be considered. The discretisation is applied to the calculation of substrate leakage currents in sub-micron LDD MOSFETs, the results of which will be presented.

Computational Simulation of Hydrodynamic Convection in Rising Bubble Under Microgravity Condition
In this work, rising of a single bubble in a quiescent liquid under microgravity condition was simulated. The related unsteady incompressible full Navier-Stokes equations were solved using a conventional finite difference method with a structured staggered grid. The interface was tracked explicitly by connected marker points via hybrid front capturing and tracking method. One field approximatio...

In this paper, analytic solutions of two-dimensional coupled Burgers' equations are obtained by the Homotopy analysis and the Homotopy Pad$acute{e}$ methods. The obtained approximation by using Homotopy method contains an auxiliary parameter which is a simple way to control and adjust the convergence region and rate of solution series. The approximation solutions by $[m,m]$ Homotopy Pad$acute{e...
متن کاملCalculation of Optimum Dimensions and Array of Submerged Vanes at Intakes Using the Feasible Direction Method
In recent years, installation of plates in canal beds have been considered for sedimentation control and bed load reduction at canal intake. These planes, called submerged vanes, are different in dimensions. They are installed at intakes in-group with reasonable distance from each other. Presence of these vanes at intakes initiate transverse shear stress on river bed and causes sediment transpo...

متن کاملMulti fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects
Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
