Moving liquid-gas interfaces appear frequently in both natural processes and engineering applications. In the case of partially filled tanks, for instance, accurate description free surface transient behavior during transportation or earthquakes is paramount importance structural stability analyses. This work presents new experimental data sloshing at laboratory scale a vertical cylindrical tank with different filling levels, along numerical simulations selected cases using an open source...
Purpose – The present work is a numerical study of breaking dam problem. purpose this paper to assess the effect turbulence and surface tension models in prediction interface position long-term analysis. Additionally, dimensional effects are analyzed by carrying out both 2D 3D simulations. Design/methodology/approach Finite volume simulations performed with different compared between them contrasted results computed using other techniques experimental data. Findings reported general good...
A transient shear stress model for the solution of water-hammer problems laminar flow in pipes is presented. The based on polynomial expansion radial profiles axial velocities, and resulting set equations by method characteristics. This approach, as compared to usual quasi-steady (which can be regarded a particular case new method), allows better representation at wall during pressure transients. present included with only minor modifications into any existing code solving problemirthat uses...
ABSTRACT It is well known that the inherent three‐dimensional and unsteady nature of turbulent flows a stumbling block for all approaches aimed at resolving their spatial temporal variability. The pseudo‐direct numerical simulation (P‐DNS) method flows, proposed by authors in previous publication, focused on variability, leaving task solving evolution to highly simplified, parameter dependent model, be adjusted case basis. Although some auspicious results were obtained, applicability P‐DNS...
The accurate prediction of void fraction profiles near solid walls using the two-fluid model is still an unresolved issue. These result from combination two factors: a) forces acting on bubbles, and, b) geometric constraints imposed by their shape. We propose herein a that involves particle-center-averaging procedure for disperse phase, and reinterpretation postprocessing results obtained. This center-averaged approach averages phase (bubbles) based particle center indicator function, while...
This paper presents experimental data for dispersed liquid/liquid upflows. Water was the continuous phase and mineral oil droplet phase. For this flow regime reduced gravity bubbly phenomena simulated because water had almost same density. The mean velocity turbulence fields, size distributions of droplets, volume fraction, interfacial area density distribution were measured using fiber optic Laser Doppler Anemometer (LDA) (PDA) systems. Significantly, results presented in are similar to...
Atherosclerosis is a disease that affects medium and large size arteries it can partially or totally obstruct blood flow through them. The lack of supply to the heart brain cause an infarct stroke with fatal consequences permanent effects. This involves proliferation cells accumulation fat, cholesterol, cell debris, calcium other substances in artery wall. Such results formation atherosclerotic plaques called atheromas, which may obstruction flow. Cardiovascular diseases, among...

An application to one-dimensional compressible flows of a general bond-graph approach for computational fluid dynamics (BG-CFD), developed in previous papers by the authors, is presented. The shock-tube problem modeled and simulated this novel approach, results are compared against available analytical solution. numerical simulation shows that, even with simple shape weight functions selected case, BG-CFD able deal really complex non-linear flow problems which all thermodynamic aspects taken...
Abstract Most of the work related to water production in oil wells found literature deals with problem determining critical flow rate for coning, but very few has been done determine above rate. Moreover, available correlations use differ considerably. The aim present study was performance a single well range operational conditions and petrophysical parameters characterizing petroleum reservoir. A simulation model radial geometry constructed, considering undersaturated including contact....

Abstract The present work describes the design of a high efficiency thermal neutron detection system, and measurements performed with it on electrolytic cells containing LiH dissolved in D2O palladium cathodes. A procedure involving use non-stationary (pulsed) current through cell caused correlated production to be observed repeatable manner. These patterns are strongly dependent previous charging history technique employed seems very useful as research tool for systematic study different...
