Species transport equation
 

I am trying to calculating residence time of distribution(RTD) in a stirred tank reactor. I initiated the species transport equation after i've solved the hydrodynamics equation. I set the properties of my tracer as the properties of the bulk fluid/flow which is water.

How can monitor this to get the time?

Also, How can introduce my tracer from the top surface of the liquid?

Expecting your reply

input the concentration of the tracer at the boundary condition if you are considering it from the inlet. otherwise if it's generation within the domain, you use a source term defined with UDF.
