CFD Simulation of Vortex–Induced Vibrations of Free Span Pipelines Including Pipe-Soil Interactions (2015-04-27)This paper presents a three dimensional numerical simulation of free span pipelines under vortex-induced vibrations (VIV) and pipe-soil interactions. Pipeline is simplified as a tensioned beam with uniformly distributed ...

(2014-06-24)The flow in a tightly packed array of spheres is important to various engineering fields. In nuclear engineering applications, for instance, researchers have proposed core geometries of the pebble bed reactor (PBR) type ...
-
(2016-05-03)Many natural and engineering systems are governed by nonlinear partial differential equations (PDEs) which result in a multiscale phenomena, e.g. turbulent flows. Numerical simulations of these problems are computationally ...

(Texas A&M University, 2005-08-29)We present methods for incorporating bubbles into a photorealistc fluid simulation. Previous methods of fluid simulation in computer graphics do not include bubbles. Our system automatically creates bubbles, which are ...
-
(2021-07-05)Poor cuttings transport in deviated wells is considered a main factor limiting drill rate; inducing excessive torque and drag; or in severe cases, resulting in stuck pipes. This study presents a computational fluid dynamics ...

(2022-04-13)Ventricular assist devices (VADs) are life-saving devices that provide cardiac support to failing hearts. However, over half of VADs are malpositioned which can lead to serious complications such as thrombus formation, ...
-
(1994)The combustion of CH4 in air is examined through the use of computational fluid dynamics modeling. The standard laminar and turbulent case conservation equations are revised or in some instances replaced with non-differential ...
-
(2020-07-20)The underground gas releases from buried pipelines can cause serious damage to the environment, properties, and population. This work aims at modelling the underground gas releases using a computational fluid dynamics ...
-
(2010-07-14)Magnetic nozzles must convert thermal or gyro energy of the plasma to thrust while also inducing plasma detachment in order to be effective. Plasma detachment and methods to induce plasma detachment are examined. In ...
-
(2014-09-24)Earth and Titan have vastly different physical environments, but similar landscapes. Sand dunes, like those found in Earth’s deserts, cover large areas of Titan’s equatorial region and are important records of climate. ...
