Computational Fluid Dynamics
Computational Fluid Dynamics (CFD) is a form of fluid mechanics that uses numerical methods and algorithms to solve and analyse problems involving fluid flow, the techniques of which are similar to finite element stress analysis. Essentially, fluid volumes are broken down into hundreds of thousands of volume elements to be analysed. The final results can then be plotted in various formats as described below.
The CFD modelling software used at Vaughan Co. for analysis is among the top programs available in the world for this type of detailed computer flow modelling work. Over the past 8 years, Vaughan Co. has evaluated well over 1000 different wastewater, sludge and bio-solids systems for use with its products. All Rotamix mixing system designs are supported by CFD analysis, either by standard modelled geometries, or using customised models individualised to meet specific application parameters on a consultation basis.
Shown as cross-sections through vertical or horizontal planes, velocity plots help to describe mixing energy distribution within the tank. Velocity plots have proven that small diameter nozzles producing high velocities provide more complete mixing than larger diameter low-velocity nozzles designs using equal amounts of energy. Higher velocities allow flow patterns to travel farther, while inducing significantly more entrained fluid. Unlike systems that use a standard non-clog pump, the Rotamix system is able to safely use smaller diameter nozzles without the risk of plugging, as whole solids are continuously reduced in size by the Vaughan mixing chopper pump.
