Hydrodynamic models are important for the design and control of wave energy converters. Traditionally they have been obtained using velocity potential/boundary element type methods, however associated assumptions of inviscid fluid, irrotational flow, small waves and small body motions are a major limitation of this modelling approach, since WECs are designed to operate over wide wave amplitude ...

We are starting publication of a series of featured articles entitled “Multiphase Computational Fluid Dynamics for Industrial Processes.” In this short Introduction we can only touch upon some of the important issues of industrial computational fluid dynamics (CFD) applications. It is difficult to underestimate the importance of CFD for modern industries. Advanced technologies require powerful ...

To delineate the influence of hemodynamic force on cell adhesion processes, model in vitro fluidic assays that mimic physiological conditions are commonly employed. Herein, we offer a framework for solution of the three-dimensional Navier-Stokes equations using computational fluid dynamics (CFD) to estimate the forces resulting from fluid flow near a plane acting on a sphere that is either stat...

Understanding and modelling of main annulus gas ingestion through turbine rim seals is considered and advanced in this paper. Unsteady 3-dimensional computational fluid dynamics (CFD) calculations and results from a more elementary model are presented and compared with experimental data previously published by Hills et al (1997). The most complete CFD model presented includes both stator and ro...

After the Montreal Protocol banned the use of chlorofluorocarbon (CFC) propellants in metereddose inhalers (MDIs), the pharmaceutical industry now has provided suitable alternatives, one of which is the dry-powder inhaler (DPI). A DPI is a device in which small doses of drug powder are delivered to the lung. The inhaled dose consists of drug particles attached to carrier particles. The drug par...

Computational fluid-dynamics (CFD) simulations have become an important tool for the 10 assessment of airflow in urban areas. However, large discrepancies may appear when simulated 11 predictions are compared with field measurements because of the complexity of airflow behaviour 12 around buildings and difficulties in defining correct sets of parameter values, including those for inlet 13 condi...

Aerodynamic performance and agility during flapping flight are determined by the combination of wing shape and kinematics. The degree of morphological and kinematic optimisation is unknown and depends upon a large parameter space. Aimed at providing an accurate and computationally inexpensive modelling tool for flapping-wing aerodynamics, we propose a novel CFD (computational fluid dynamics)-in...
