Free Surface CFD Simulation Of Gasoline Sloshing In A Tank

01 February 2021, 11:00 am

You are in the business of transporting liquids via the road in tankers. That liquid can be anything from harmless water to inflammables like gasoline. Hauling liquids by road also presents challenges such as inertial loads, frequent stop-starts and sudden braking incidents.

Whilst sloshing, the liquid exerts a dynamic force on the container, which may cause leakage or damage the container and/or its support structure. Sloshing is a highly nonlinear and random process depending on numerous factors such as vessel motion, liquid volume, material properties, and container geometry.

The following example shows a truck carrying gasoline braking from 60mph to 0mph and the sloshing of fluid in the tank.

A few things we help you with:

  1. Reducing dangerous influences on the directional dynamics and improving safety performance of vehicles
  2. Understand and assess the hydrodynamic forces and moments arising from liquid cargo oscillations in tanks under various manoeuvres and their impact on vehicle stability
  3. Improving designs and controllability of partially filled tank vehicles
