Default Adding Curvature Induced Flux in Diffusive Flux Model for Shear Induced Migration

rpIITG is on a distinguished road
I want to add curvature-induced flux to the total migration flux in the Diffusive Flux Model equation for shear-induced particle migration.
The equation for curvature-induce flux is given by:
N_{c} =K_{r}n \kappa a^{2} \dot{\gamma}\varphi

Where n is the unit normal vector in the radially outward direction in a curved streamline shear flows \kappa is the curvature of the streamline.

Can somebody help me to implement the above equation in OpenFOAM?

I really appreciate any help you can provide.

Thank you!
