Radioisotope concentration in convective flow
Hi everyone!
I have been trying to calculate the steady-state concentration of the radioactive isotope of nitrogen N-16 in the coolant of a pool type experimental reactor. The isotope is created by the absorption of a neutron in O-16 and a subsequent emission of a proton. The reaction takes place in proximity of the reactor core, the nitrogen is then carried around by the convective flow and decays with time. I have created an additional variable and so far managed to simulate its transport by the fluid. How could I specify the decay term (of the form -lambda*c, where c is the concentration of the isotope) in the transport equation? Thank you! Rimidalv |
Hopefully a source term can do this. With luck you can apply the source term across the whole domain.

Hi again!
I think I got the problem solved. I did not know that a subdomain in the fluid has to be created, in which a source term can be specified. I am currently running the simulation and will let you know whether it has worked. Thank you for the suggestion! Rimidalv |
