A continuous surface tension force formulation for diffuse-interface models
We present a new surface tension force formulation for a diffuse-interface model, which is derived for incompressible, immiscible Navier–Stokes equations separated by free interfaces. The classical infinitely thin boundary of separation between the two immiscible fluids is replaced by a transition region of small but finite width, across which the composition of the one of two fluids changes co...
متن کاملWhy Believe That There Is a God?
This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
متن کاملA surface tension sub-grid model for phase interface dynamics
This paper reports on the development of a model for the sub-filter surface tensioninduced motion of liquid/gas phase interfaces. A key feature of the proposed model is to take the sub-filter phase interface dynamics fully into account by employing a dual-scale approach. Instead of modeling the sub-filter phase interface geometry, it is resolved on an auxillary grid using the Refined Level Set ...
متن کاملa 10-bit 50-ms/s parallel successive-approximation analog-to-digital converter
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
15 صفحه اولSurface layering of liquids: Is surface tension the dominant factor?
Recent measurements show that the free surfaces of liquid metals and alloys are always layered, regardless of composition and surface tension, a result supported by three decades of simulations and theory. Recent theoretical work claims, however, that at low enough temperatures the free surfaces of all liquids should become layered, unless preempted by bulk freezing. Using x-ray reflectivity an...
