Análisis del comportamiento fluido-estructural en condiciones dinámicas de un tanquero con capacidad de 10000 gal, para el transporte de combustible, utilizando el método computacional transitorio

Abstract

The present research work aimed to analyze the behavior in dynamic conditions of a large tanker for the transportation of fuel, using CAE (Computer Aided Engineering) simulations using the transient computational method of fluid-structural interaction. Two simulation conditions were proposed to see the sloshing effect of the fuel. The first condition is to verify the behaviour of the fuel fluid by introducing values for the conditions of longitudinal hard braking of the truck. The second condition is to see the behaviour of the fluid when a sharp turn occurs during cornering. The virtual tests carried out in the LS-DYNA software are composed of two groups for the different conditions in the sloshing event. Each group consists of four models from A to D representing the models of attenuators to the movement of the fluid. The simulations carried out using the ALE (Arbitrary Lagrangian-Eulerian) methodology allowed to abtain data and verify that the proposed designs project decreasing values of the sloshing effect. Within the results, the maximum values for pressure and speed were considered. Consequently, when comparing the model values, in could be observed that the model with the lowest value within the maximum values for braking and turning acceleration was the most suitable model based on its values that relate the geometry in the tank for the case study. It was concluded that models with larger cross-sectional area reduce the analysed phenomenon. Finally, the CAE computational methot is recommended with the ALE method to reduce economic and physical resources.
