Application: Novel Gas Meter Designed Using EFD.Lab Flow Simulation Software
Posted Mon October 16, 2006 @10:50AM
Print version Email story Tweet story
Application Actaris used EFD.Lab computational fluid dynamics (CFD) software from Flomerics to design innovative gas meters. Actaris fluidic meters work on a unique principle of putting an obstacle in the flow stream and using a sensor to measure the resulting oscillations to determine the flow rate.

EFD.Lab enabled Actaris engineers to quickly and accurately simulate the flow velocity, direction and pressure, making it possible to evaluate new design concepts without the expense and leadtime required to build multiple prototypes, said Ibne Soreefan, Project Manager for Actaris. EFD.Lab also provided far more diagnostic information than can be obtained by testing a prototype, enabling engineers to move more directly to an optimized design.

CFD Analysis Piques Interest in Tidal Power

News The massive 30-foot tides of Alaskas Cook Inlet and the resulting ebb and flow of powerful tidal currents break up sea ice, shorten ship transit times in the inlet and provide an unforgettable spectacle for tourists. But could these tides also become a significant electrical energy generator for the state?

A Petroleum News article describes how researchers have used CFD to assess the operation of different turbine designs and turbine farm configurations at each specific tidal power site, prior to testing the site using actual equipment.

Application: The Best CFD Averaging Methods for Distorted Flow Fields
Posted Tue October 10, 2006 @05:23PM

Application By Mark Anderson,
VP of Software Development,
Concepts NREC

Which averaging technique will best characterize performance in CFD flow fields where distortion is observed?

Three-dimensional flow fields typically have some degree of distortion in the flow properties and flow profiles across a given cross section. These distortions can be quite significant in localized regions, for example at the exit plane of a radial compressor impeller. Because most designers are interested in averaged values of performance, the question often arises as to what averaging technique is the best to use.

Help with 2D UPWIND Solver
Posted Mon October 09, 2006 @08:38AM
Print version Email story Tweet story
Help Desk tizianoghisu writes "I am trying to write a 2D solver for the Euler equations (initially ...) for simulating the flow inside a channel (or duct). Because the problem is advection dominated (even when I will introduce the stresses ...) I chose to use an upwind discretisation for the fluxes to avoid using artificial viscosity to stabilise the solutions. Initially I am trying a simple 1st order UPWIND (or cell-donor scheme), I might improve it later.

Everything works in 1D, but not in 2D. I guess the problems comes from the fact that the flow is more or less in the same direction of the pseudo-horizontal cell boundaries, and this gives me trouble when discretising the flux through the north and south boundaries.

Any suggestion on how to solve the problem pratically?

Thanks in advance"
