simulation with two interacting airstreams, how to set up ?

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
