Similarly, each Boundary Condition will let you choose which fluid will enter the system at that opening.

Once you’ve enabled the option, you’ll then be able to select which fluid- the air or gas- is present at the start of the analysis (using the Free Surface capability requires a transient analysis). I’m using this new capability to perform a tank filling simulation so I can confirm the tank will fill as quickly as I want, and get an idea of how powerful my pump needs to be. When proceeding to the Fluids tab and selecting both a gas and liquid, such as air and water, the Default fluid type will now show as “Immiscible mixture” – meaning they can now occupy the same volume. When creating a new project, you’ll be able to select this option at the Analysis Type menu. Until now, it has only been possible to mix fluids of the same phases (gasses with gasses, liquids with liquids), which mean it was impossible to simulate any system with a free-flowing liquid surrounded by a gas- for example, water sloshing in a tank, or aeration in a static gas-liquid mixer.Īll that has changed with SOLIDWORKS 2018, with Flow Simulation’s new “Free Surface” capability. In mixing problems, such as exhaust gas recirculation or blending liquids, it’s always been possible to see mass or volume concentrations, density changes and more- even with as many as ten different fluids- but there was always one major caveat. Engineers commonly use Flow Simulation while designing such components to ensure a certain fluid delivery rate, minimize pressure resistance and select the right pumping equipment- even including certain processes like heat transfer or mixing of fluids.
For customers of Hawk Ridge Systems, one of the most popular uses of SOLIDWORKS Flow Simulation has long been predicting the performance of hardware and industrial equipment – things like valves, manifolds, and piping systems.
