Lagrangian multiplier in ALE moving mesh (2D axisymmetric)

Please login with a confirmed email address before reporting spam

Dear all,

I have a question about the application of the Lagrangian multiplier for the species flux across an interface separating two fluids in ALE moving mesh. I want to set c_lm (mol/m^2 s), weighted by the molar mass M_w (kg/mol), as the source of mass at the fluid-fluid interface. The problem must be solved considering axial symmetry (2D axisymmetric). So, in this case, should c_lm be corrected as c_lm/(2 * pi * r) when applied at the fluid-fluid interface?

Best regards, NP
