Estudio para analizar la factibilidad de empleo de modelos numéricos en la determinación de los coeficientes de fricción de la bomba jet en campos del oriente ecuatoriano.

Abstract

In the present work we intend to use appropriate mathematical models, which can be employed because of their inherent relationship to the subject of study. It should be emphasized that each mathematical model is different, and its accuracy can be influenced by a wide range of factors. Each model requires a different set of variables, which are established according to the theoretical basis considered and the mathematical relationship between variables present in the system. The models used in the study were the mathematical model of the University of Tulsa and ANSYS Fluent, the latter allows us to establish or generate a numerical model based on the physical phenomena and other characteristics included in the case study. The study was started using the numerical model through the ANSYS Fluent tool. This first section of analysis allowed us to corroborate the validity of the use of numerical models in our object of study, through the comparison of results with real information. We started the study with the ANSYS Fluent model because its mathematical structure and fundamental basis places it as one of the most reliable and used numerical models in the world due to its strength and accuracy. The second stage involved the less accurate model, the Tulsa model; this was developed in two application parts, a Calibration stage, and a Validation stage. This allowed us to analyze the accuracy of the model based on friction coefficients determined after the process.
