I'm a novice at COMSOL and am struggling to achieve this simulation.
I'm attempting to essentially mimic the model of fluid flow past a sphere, but with air being released through "holes" along the edge of the sphere. Ultimately, I would like the sphere to be able to expand as a hyperelastic material as well. I haven't been able to achieve a successful model combining two separate fluid domains. Would greatly appreciate suggestions for what Multiphase Flow setup I should be using and any tricky COMSOL factors to consider!

Dear Joanna, I suggest looking into our paper http://www.sciencedirect.com/science/article/pii/S0377042715000242 and poster https://www.comsol.com/paper/modelling-of-reactive-non-isothermal-mixture-flow-and-its-simulation-in-comsol-m-19013. although our model setting is quite different from yours, I think you can learn a lot about the underlying governingn equations.
