Consistent numerical diffusion terms for simulating compressible multicomponent flows.

Highlights: [•] A new interface-capturing method is proposed for compressible multicomponent flows. [•] A high-order central difference scheme is applied. [•] Consistent numerical diffusion terms are analytically derived. [•] Pressure, velocity, and temperature equilibriums at interfaces are maintained. [•] Several one- and two-dimensional problems are used to verify the proposed method. [Copyright &y& Elsevier]
