ITURBIDE JIMENEZ, F.; MENDOZA JASSO, A.J.; ANTONIO GARCIA, A.  and  SANTIAGO ALVARADO, A.. Design and construction of an apparatus to visualize incompressible fluid flow in several regimes. Rev. mex. fís. E [online]. 2018, vol.64, n.2, pp.133-138. ISSN 1870-3542.

In this work, the design and construction of a didactic experimental equipment to visualize the fluid flow behavior in the laminar, transition and turbulent regimes is presented; as well as the ability to measure and display the respective Reynolds number (Re) of each flow; current educational equipments have limited or null capacity in this regard. The equipment was designed taking into account the basic laws of fluids such as mass, momentum and energy conservation. The analytical calculations were numerically validated using the finite element method (FEM), for which the Ansys software was used in its Ansys® Parametric Design Language (APDL) and Workbench platforms. Solidworks tools for conceptual design and Stratasys Catalist for three dimension (3D) printing were used. Additionally, hardware was implemented for the step of measuring the flow velocity, temperature and Re calculation. The apparatus is a valuable resource in fluid flow visualization since it permits to read several fluid parameters immediately from a display.
