Опыт изучения нефтяных месторождений, приуроченных к отложениям баженовской свиты, показывает, что продуктивность нефтенасыщенных пластов является существенно неоднородной как по площади, так и разрезу месторождения. Выявление зон повышенной продуктивности в отложениях свиты одной из первоочередных задач вовлечению разработку значительных, но трудноизвлекаемых запасов, свиты. С целью выявления ...

Numerical models are essential tools for the study and analysis of hydrodynamics estuarine systems. However, model results contain uncertainties, which need to be minimized increase accuracy predictions. In this work, ensemble technique is proposed as a solution improve hydrodynamic forecasts regions. Two numerical models, openTELEMAC-MASCARET Delft3D, were considered application two Portuguese...

Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...

Diffuse correlation spectroscopy (DCS) is a non-invasive optical technique capable of monitoring tissue perfusion changes, particularly in the brain. The normalized temporal intensity autocorrelation function generated by DCS is typically characterized by assuming that the movement of erythrocytes can be modeled as a Brownian diffusion-like process instead of the expected random flow model. Car...

This study aims to incorporate most recent multiphase models in order to investigate the hydrodynamic behaviour of a TBR in terms of pressure drop, liquid holdup and catalyst wetting efficiency. Taking into account transport phenomena such as mass and heat transfer, an Eulerian k-fluid model was developed resulting from the volume averaging of the continuity and momentum equations and solved fo...

the aim of this paper is to study the local nusselt number of the symmetrical liquid-liquid jets emitting from a nozzle. equations obtained from theoretical works are arranged in the form of a computerized model. the validity of this model was tested by the data from an experimental paper [1]. after few adjustments the model predicted the experimental data with a reasonable accuracy. making sur...

New quantum hydrodynamic equations are derived from a Wigner-Boltzmann model, using the quantum entropy minimization method recently developed by Degond and Ringhofer. The model consists of conservation equations for the carrier, momentum, and energy densities. The derivation is based on a careful expansion of the quantum Maxwellian in powers of the Planck constant. In difference to the standar...

The effect of hydrodynamic interactions on the free-solution electrophoresis of polyelectrolytes is investigated with coarse-grained molecular dynamics simulations. By comparing the results to simulations with switched-off hydrodynamic interactions, we demonstrate their importance in modelling the experimentally observed behaviour. In order to quantify the hydrodynamic interactions between the ...
