Modeling Consumer Products Applications

Free-surface flows are common in the design and manufacture of products used in both the home and office environment. Bottle filling is, for instance, a process which takes place on a large scale everyday. Designing such a process to minimize waste while maximizing production speed can lead to significant cost savings over time. FLOW-3D's free-surface modeling capabilities make it possible to realize those savings.
FLOW-3D can also be used to design spray nozzles, model absorptive capabilities of porous materials and many other components or capabilities of consumer goods.
Numerical methods used to solve the equations for fluid flow and heat transfer most often employ one or more iteration procedures. By their nature, iterative solution methods require a convergence criteria that is used to decide when the iterations can be terminated.
In many cases, iteration methods are supplemented with relaxation techniques. For example, over relaxation is often used to accelerate the convergence of pressure-velocity iteration methods, which are needed to satisfy an incompressible flow condition. Under relaxation is sometimes used to achieve numerically stable results when all the flow equations are implicitly coupled together. Read more in CFD-101 >
