The problem motivating the current work is a mould filling during casting process. The aim of our analysis is to provide a simple experimental model simulating the main flow characteristics accompanying such process. Hence, the hot fluid is supplied under high pressure into an inclined box. Fluid flows inside the box between two cold isothermal walls, passing obstacles simulating internal compl...

In this article, we assume that the force field acting over a fluid is periodic on time and the velocity of the liquid is zero at spatial infinity. We prove the existence of time-periodic solutions to the system governing the motion of an incompressible fluid filling the whole space.

We present a novel method for solving the incompressible Navier-Stokes equations that more accurately handles arbitrary boundary conditions and sharp geometric features in the fluid domain. It uses a space filling tetrahedral mesh, which can be created using many well known methods, to represent the fluid domain. Examples of the method’s strengths are illustrated by free surface fluid simulatio...

PURPOSE To evaluate magnetic resonance (MR) hydrometry, a method of quantifying fluid amounts by using MR imaging, for assessing the exocrine function of the pancreas after stimulation with secretin. MATERIALS AND METHODS Images were obtained with a single-shot turbo spin-echo sequence by using a 1.0-T magnet with a quadrature body coil. Image postprocessing and evaluation were performed at a...

In order to reveal the mineral filling sequence and fluid action process in dissolution pores of bedded siliceous rocks Dongrong Formation Sanjiang Basin, petrological characteristics, geochemical analysis testing methods were comprehensively applied research, databases major amount rare earth elements established, sedimentary environment, origin source materials systematically judged again. Th...

The success of any nanoimprint process depends upon its ability to exactly reproduce the template pattern. Thus, complete filling of recessed features in the template is an important issue that is controlled by the dynamics of the flow through these sharp structures. At these small scales, capillary forces are large and must be included in the fluid flow model. The mechanism of interface advanc...

In two different experimental environments the isolated turtle ventricle was found to fill and eject blood in the absence of a positive filling pressure. It is concluded that the ventricle can "suck" fluid using energy liberated from its wall during diastole. T HE question of ventricular "suction," that is "Does energy derived from the ventricle contribute to its filling in diastole?" has been ...

The important diagnostic significance of filling defects of the temporal horn is well illustrated in the two cases here described. Both patients were middle-aged men with few neurological signs but with raised intracranial pressure and a moderate increase in cerebrospinal fluid cells and protein. In both cases the local cerebral symptomatology indicated a diencephalic disturbance. Ventriculogra...
