摘要：
Three Finite Volume schemes are proposed in this note to satisfy the maximum principle for the mass fraction y , solution of an unsteady balance equation, including a relative velocity between phases and a source term. The continuous maximum principle is examined first. Then, linear implicit discrete schemes are detailed in a multi-dimensional and unstructured framework.
