interface len. scale
 

hi
I am simulating multifase flow in channel
I can not understand what is interface len. scale
please help me

This is described in the documentation - have you read it?

The multiphase flow is assumed to be droplets or bubbles. Either way they are charaterised by a diameter, or at least a representative diameter. This is the interface length scale.

hi
thanks you
I have read theory guide
I am mixing to fluid with water properties symmetrically
can i use below formula?
Attachment 22342
mean diometer of water is 10 micron
r=?
maybe r=0.5
