Thanks to the existing computer simulation tools, the Finite Element Method (in short FEM)
combined with Fluid Flow Simulation Module are applied to adjust the rotor’s parameters essential
for fluid flow systems. Such parameters ought to take into account an impact of the flow conditions on
the level of aeration for the flowing water. The FEM is a currently commonly used computer
simulation tool for many engineering computations. The development of FEM evolves simultaneously
with the progress of the computer techniques. The applied herein computer aided design technology
resorts to FEM and Flow Simulation Module used for fluid flow modeling in the systems of biological
purification of sewage. SolidWorks Flow Simulation is a perfect tool for an engineer who wishes to conduct a fluid flow analysis, but is not an expert within fluid simulation. SolidWorks Flow Simulation can be used in a diverse range of applications and is designed to be an extremely flexible software tool. If one strives to develop the machines, by using SolidWorks Flow Simulation during the product development cycle, it can help to build a better product within less time. Flow Simulation is a goal based flow analysis software. One simply instructs the program about the main designer’s objectives e.g. maximal velocity in flow, specific pressure drops across examined model etc. and this software package will calculate these required goals and present all computed results to the user after the completion of the analysis. This functionality helps the potential user to obtain a much deeper engineering insight into designs.
This type of modeling-based research enables the adjustment of the efficiency in the designed devices
and systems tuned up to the real recipient’s demands. Equally, it also allows to decrease the energy
consumption for the new innovative technological solutions which in particular meets the current high
standard EU requirements . The paper discusses the adjustment of the rotor construction and its working parameters in modeling processes matters for the determination of the properties and parameters of such devise, which is meant to operate non-stop within the entire interval of the real time and to ascertain to them the most favorable conditions for aeration and turbulence of the flowing fluid.
