Hello forum,
I am new to Flow Simulation, and since we can use it at our university I tried to experiment with the following setup (image):
Two air flows from different directions. Flow one is 1.6 m/s. Flow two starts inside of the jet nozzle object and exits the nozzle with about 10-20 m/s. I am interested in how the two flows interact with each other, and if flow 2 can prevent flow 1 from reaching the object, or rather how fast flow 2 has to be to do so.
I think it is pretty simple but somehow I can't manage to get it to work. I tried it with a mixture of internal an external flows, and with two internal flows (modeling a huge box around it, but I didn't know excactly where to set the outlets).
If it is an external flow setup with an internal flow included, do i have to set a outlet lid on top of the nozzle? How could I get this to work ?
Thank you and have a nice day!

Thor -
you will need to use an external simulation. External allows both internal and external flow conditions, but internal only allows internal flows.
You will set boundary conditions on the 2 solid surfaces such that the arrows point in the direction of flow and define either the velocity or mass flow rate, etc.
With an external simulation it will solve how those flows interact with the ambient out until the limits of your computational domain.
