The particle visosity does influence the breakup mechanism. But considering the point mass approach of DPM, it is not a good idea to use the same shear-dependent law. The point masses does not enclose flow within them, that causes shear.
Actually, the code check makes sure one uses the same viscosity definition for both VOF and discrete phase, when using the transition model.
