Hi,
I'm trying to model the rupturing of a 2 diaphragms in a shock tube. The 1st diaphragm separates the driver gas from the driven gas, and I can initialize the driver and driven gas with different initial pressure and simulate its rupturing at t=0. However, there's also a secondary diaphragm which is connected to a nozzle downstream. It should rupture when pressure around it reaches 100kPa, according to literature. How can I simulate this in OpenFOAM? Thanks in advance. |
