New challenges in engineering teaching require a multidisciplinary training of future engineers through the incorporation of computer resources that enable the modeling, simulation and design of real physical systems. The teaching methodology that provides to these new requirements, should consider the implementation of modelling and simulation tools, to offer a form of updated engineering work and according to technological advancement.The approach of multidisciplinary teaching in engineering careers should relate the contents and concepts taught in class with real projects in the engineering field, with the purpose of enriching the training of the professional future, through the use of tools for the detection of the relevant variables in a problem, interpret, and propose solutions to different alternatives increasing their capacity for analysis, and above all for the rational selection of proposals, and taking decisions based on the solutions found.

The proposal presented aims to show a work in an integrated manner using Design CAD (Computer Aided Design) and a multiphysics software simulation, CFD (Computer Fluid Dynamics), with the purpose to study the fluid dynamics of an equipment, in this case the distribution of flow velocity patterns in tube condensers, to analyze the erosion-corrosion mechanism in tubes to eliminate faults by modifications on design.

The advantages of working with simulation platforms replaced the work of analytical resolution, where the amount of variables involved makes very complex analysis. This methodological proposal suggests an important breakthrough in process engineering, since is used the development of simulation tools for product design through platforms that incorporate calculation by finite element and computational fluid dynamics.

To simulate the operation of equipment, in order to obtain the desired performance optimization. COMSOL Multiphysics platform allows us to import models from designs of solids such as SOLID WORKS programs. This interaction between programs is very useful for the design of complex geometries. The designed models for different air intakes are analyzed taking into account that the assumptions about the behavior of the density changes of pressure and/or temperature are very important in the study of flows. Application to fluid module is intended for incompressible, however admits small changes in density caused by temperature variations. They are presented in 3D, in the final work, different models designed for different velocities, and flux flow variations and the analysis of the mass flow rate input that defines the choice of the appropriate design.
