What Is Additive Manufacturing?

Posted December 31, 2024 at 01:33 by Kevin Cooper


If you ask what additive manufacturing is, it is a technique for creating three-dimensional products from CAD models by layering material using digital data.

previously known as rapid prototyping, and currently popular as 3D printing. The term Rapid prototyping was coined to describe the time efficiency of the AM process and technology which created physical prototypes directly from digital...

Understanding The k-ω SST Model

Posted May 18, 2017 at 16:38 by Avr.Tomer

Florian Menter's k-ω SST is one of the most reliable and trusted RANS two-equation eddy-viscosity turbulence models for the simulation of attached boundary-layer flows with adverse pressure gradient, and also serves as first choice for hybrid RANS-LES DES by many.

The following taken from CFD ISRAEL blog (thoughts of a CFD blogger) is intended to give a short and thorough review of the main reasons for the k-ω SST*Model popularity.

Wind Tunnels and CFD

Posted April 9, 2009 at 09:41 by gocarts
Updated April 9, 2009 at 09:43 by gocarts (Embedded image)

To many observers the rivalry between wind tunnels and CFD is a zero-sum game - as CFD matures it simply replaces wind tunnels. However, this is far from the truth. Often you'll find wind tunnels and CFD used together in a symbiotic process where one technique fills in knowledge gaps left by the other.
