apply different flow rate in two inlet in Fluent with varying time
apply different flow rate in two inlet in Fluent with varying time
(OP)
Hi all.
Currently, I am doing micro valve analysis which contains two inlets. the conditions I have to apply in those inlet are different flow rate with varying time.
For example,
Inlet-1 = 8 ul/min mass flow rate from 0-3 seconds.
inlet-2 = 4 ul/min mass flow rate from 3-6 seconds.
My question is whether I have to create UDF to solve this or any default option is available in Fluent.
thanks in advance
Kind regards

You can check the values in a graph to see if everything looks right but I find inputting them to be easier in the text editor. You will need to be sure you specify the units correctly. You will also need to include ramping up and down of the flow rate as I have shown in the example since Fluent won't accept two flow rates at the same point in time. I used a 0.1 second ramp but you can make it much smaller.
