3D Modeling and Numerical Simulation of a Water Softener Device

Abstract

Water treatment in the magnetic field is not an officially recognized method of water softening. This method can be promoted as an alternative to water softening without potentially toxic chemical agents. The water softener device consisting of 3 pairs of permanent magnets made of neodymium was designed with the help of Solid Edge software. Numerical simulation was performed using ANSYS WORKBENCH finite element analysis software using the FluidFlow (CFX) module. With this analysis module the dynamic analysis of the fluid flow through a pipe was performed. Three numerical analyses of the water flow through a pipe with an internal diameter of 20 mm were performed at a pressure of 2 bars, namely: • the water flow without magnetic influences; • the water flow under the magnetic influence of the softener device positioned longitudinally with the pipe; • the water flow under the magnetic influence of the softener device positioned transversely with the pipe. The conclusions of these simulations can be the basis for future research in order to optimize this type of device.
