The paper presents data on the influence of additives of the pre-treated aluminium oxide powder on the structure of cast lead-tin-based bronzes.
The conclusions of these simulations can be the basis for future research in order to optimize this type of device.
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: With this analysis module the dynamic analysis of the fluid flow through a pipe was performed. finite element analysis software using the FluidFlow (CFX) module. Numerical simulation was performed using ANSYS WORKBENCH.
The water softener device consisting of 3 pairs of permanent magnets made of neodymium was designed with the help of Solid Edge software. This method can be promoted as an alternative to water softening without potentially toxic chemical agents. Water treatment in the magnetic field is not an officially recognized method of water softening. At the end, we will summarize our experience with the three programs.KeywordsTechnical drawingCSGPartEducationCAD In this communication we will do the 3D model and draft of two parts using Solid_Edge ST2021, Onshape and AutoCad. We consider it is very interesting to compare them with the aim of being the most indicated for our students, always considering the kind of design they must afford. Three powerful CAD programs with free educational version have been used to design the 3D model and the draft. This communication presents a tool, Constructive Solid Geometry, which provides the student with a systematic way to analyze a part in order to draw the necessary views and dimensions so that the part is completely dimensioned. On the other hand, as teachers with long experience of first year in the Higher Technical School of Industrial Engineering of the UPM (Polytechnic University of Madrid) we have observed that new students have little knowledge in this special aspect of Technical Drawing. Obviously nowadays models in 3D and drafts are done with CAD software. These standards concern many aspects as needed views, cutting planes, auxiliary views, dimensions, etc. International ISO standards indicate the way drafts must be correctly drawn. For an Industrial Engineer it is important to have some basic knowledge about standards in Technical Drawing concerning drafts to define a part or an assembly.
