Determinación del ángulo de la veneciana óptimo de una aleta veneciana con tubos elípticos

Abstract:

Heat exchangers are an essential component in many of the vital processes of our daily lives. The following work is directed to the study of compact heat exchangers, specifically those with elliptical tubes and louver fins. Through numerical simulation it is intended to obtain the thermo-hydraulic behavior of louver tube-fin geometries. Model inlet velocities corresponding to low Reynolds numbers (less than 1000 based on hydraulic diameter) are studied. The behavior ofthese geometries is simulated through the use of Computational Fluid Dynamics techniques. Establishing of the necessary boundary conditions to solve the equations as well as meshing of all models are described. The fin efficiency was determined according to the Schmidt method and the different models were compared regarding their thermohydraulic behavior.
