Equation (4) in the original paper contains errors. The correct equation is given as follows: 
Ds0D=2.9r2s¯+2.52Ns+1.34Nsr2s¯+0.044Nsb4¯+0.044NsPRb4¯+1.34Ns1.34Nsr2s¯5.82.311.84Ns
(4)

The supplementary material of the paper [19] has been updated accordingly and now also contains ready-to-use MATLAB functions for Eqs. (3) and (4).
