Fluid-structure interaction simulation of prosthetic aortic valves : comparison between immersed boundary and arbitrary Lagrangian-Eulerian techniques for the mesh representation [PDF]

, 2016
In recent years the role of FSI (fluid-structure interaction) simulations in the analysis of the fluid-mechanics of heart valves is becoming more and more important, being able to capture the interaction between the blood and both the surrounding ...

Large droplet impact on water layers [PDF]

, 2004
The impact of large droplets onto an otherwise undisturbed layer of water is considered. The work, which is motivated primarily with regard to aircraft icing, is to try and help understand the role of splashing on the formation of ice on a wing, in ...

Application of CLEAR-VOF method to wave and flow simulations

Water Science and Engineering, 2012
A two-dimensional numerical model based on the Navier-Stokes equations and computational Lagrangian-Eulerian advection remap-volume of fluid (CLEAR-VOF) method was developed to simulate wave and flow problems. The Navier-Stokes equations were discretized

Assessment of inlet efficiency through a 3D simulation: numerical and experimental comparison [PDF]

, 2016
Inlet efficiency is a requirement for characterizing the flow transfers between surface and sewer flow during rain events. The dual drainage approach is based on the joint analysis of both upper and lower drainage levels, and the flow transfer is one of ...

Particle detection in VOF-simulations with OpenFOAM

SoftwareX, 2020
The aim of this work is to improve the particle detection in the phase field of volume of fluid (VOF) simulations included in OpenFOAM. The reliable evaluation of the particle properties is a prerequisite for coupling the VOF method for the primary ...

Effects of an on line bypass oil recycler on emissions with oil age for a bus using in service testing [PDF]

, 2001
A method of cleaning lubricating oil on line was investigated using a fine bypass particulate filter followed by an infra red heater. Two bypass filter sizes of 6 and 1 micron were investigated, both filter sizes were effective but the one micron ...

The Gas‐Liquid Separation Characteristics Inside a Drainage Self‐Priming Pump Under Different Discharge Valve Openings

Energy Science &Engineering, EarlyView.
To investigate the influence of discharge valve opening on the self‐priming characteristics of a self‐priming pump, numerical calculations are conducted for four different discharge valve openings based on a circulation piping system. The hydraulic performance and the internal flow characteristics during self‐priming process are obtained.
