Collapsed data of the relative $\tau /{\tau }_A+1$ vs. ${\left(u_A^2/\langle u^2\rangle \right)}^{\alpha /2}$. The data include the pure polymer melts at constant pressure $P=0$ and $P=1$, thin films with rough and smooth surfaces, and attractive NP nanocomposite systems. The symbols represent the simulated data points and the dashed line represent their linear relationship. (Inset) Variation of τ vs. $\langle u^2\rangle$.
