I simulated the bubble reactor and I consider the bubbles as dem particles. The bubbles came out from the inlet at a certain velocity, the diameter of bubbles are treated as constant. How can I insert the bubbles to make them fit the certain velocity conditions? Can the insert_stream command works it out?
Another problem： there are three inlets in the reactor which bubbles inject into reactor in three different directions at the same time. The insert_stream can define the velocity of bubbles in the form of vector, but how can I dfine bubbles' three different velocity at the same time? The commands in liggghts are Sequentially executed.
Thank you for your opinions!
Thanks,
Zhao

Hi Zhao,
Hi Zhao,
>> Can the insert_stream command works it out?
you can use a certain velocity distribution (constant, gaussian) for fix insert/stream, see doc for details
>>The insert_stream can define the velocity of bubbles in the form of vector,
>>but how can I dfine bubbles' three different velocity at the same time?
You would then need need 3 fix insert/stream commands, e.g. to have different bubble velocities for different bubble diameters
Please note that you should think about the interaction of your "bubbles", e.g. you would have to implement/modify a pair style to model coalescence
