Greetings,
I am trying to implement the drift-flux model using a passive scalar approach in STAR-CCM+ by adding the slip velocity source through field functions.
And, I am using the approach proposed by Lai and Nazaroff (2000) to model the near-wall deposition. But I am not able to achieve the deposition. I am facing issues with the boundary condition of the passive scalar at walls. If I provide a flux value generally the domain got filled up with the passive scalar. Kindly provide any suggestions to overcome this problem.
Lai, A.C.K., Nazaroff, W.W., 2000. Modeling indoor particle deposition from turbulent flow onto smooth surfaces. Journal of Aerosol Science 31, 463–476.
Thanks in advance.
