Effect of Baffles on the Sloshing in Road Tankers Carrying LPG: A Comparative Numerical Study

Abstract

This work presents a comparative numerical study of the effect of using baffles, and its design, on the behavior of sloshing in a partially filled road tanker carrying LPG. Navier-Stokes equations and standardk-εturbulence model are used to simulate fluid movement; the Volume of Fluid (VOF) method is used to track the liquid-gas interface. Velocity distributions, sloshing stabilization times, and contours of turbulent kinetic energy, which are of high importance in choosing the best design of baffles, are shown. The results show sloshing stabilization times of 22 and 21 s for road tankers with cross-shaped (Type I) and X-shaped (Type II) baffles, respectively, finding lower values of turbulent kinetic energy for Type II design, being, therefore, the best design of baffles for damping of sloshing and vehicle control among studied ones.

Analysis of a Symmetrical Ferrofluid Sloshing Vibration Energy Harvester

“…Sloshing has typically been an area of interest for the shipping industry, the automobile industry, and intergalactic rocketry [13]. Most of these applications have tried to mitigate the effects of sloshing since, at large scales, a sloshing fluid can cause significant structural damage to the container [15]. Therefore, most research about sloshing has been conducted to mitigate the effects of sloshing using baffles, etc.…”
