Initial Conditions: The tank is considered to be moving laterally in the +X direction. Design 1 (left), Design 2 (middle), Design 3 (right). Design three combines both designs, expanding it’s longitudinal surface area for a total open area of 2575in².įigure 1. Design 1 and Design 2 have an open surface area of 1830in² and 1980in² respectively. SetupĪ baseline design with no baffles is compared against three separate baffle designs. In the small amount of time the majority of the movement takes place, in this scenario less than 10 seconds, evaporation, condensation, droplets, and meniscus formation are considered negligible. Concepts not included in the calculation are any phase transitions, like the water evaporating into vapor, and any surface tension, like water droplet formation and adhesion.
#Solidworks flow simulation pressure issue free
The interface between the two is called a free surface – a name used by SOLIDWORKS Flow Simulation to refer to the calculation method included in the program.įree Surface with Flow Simulation allows users to simulate free surfaces using the Volume of Fluid technique, thus allowing us to track the sloshing of a tank over time. The tank contains two immiscible and homogenous fluids, like water and air. How much force does it apply on the tank? How long does it take to dissipate? Could a particular baffle design within the tank reduce the overall force, turbulence, and time to settle? We can find out more about tank sloshing using SOLIDWORKS Flow Simulation. The liquid inside its tank continues forward, slamming into the walls, then dissipating over time in waves. A partially filled tanker travels at speed, and then suddenly stops.
