Erratum for “Transport Equation for Suspended Sediment Based on Two-Fluid Model of Solid/Liquid Two-Phase Flows” by Deyu Zhong, Guangqian Wang, and Qicheng Sun

In the section “Governing Equations for Solid/Liquid Two-Phase Flows,” the interfacial momentum balance condition for Eq. (2) is not in the correct form. Generally, the equation for momentum conservation of two-phase flows iswhere the interphase action $f_{ki}$ satisfies $f_{fi}+f_{pi}=0$. In the paper, because $F_{ki}$ is defined as $F_{ki}=f_{ki}/{\rho }_k$ in Eq. (2), the correct form of the interfacial momentum balance condition is $f_{fi}+f_{pi}={\rho }_f{F}_{fi}+{\rho }_p{F}_{pi}=0$ instead of $F_{fi}+F_{pi}=0$. This error only occurs in the declaration of variables, and the interfacial momentum balance condition is not used elsewhere; thus, the rest of the paper is not affected.
