Gaseous mixture slit flow at intermediate Knudsen numbers

The problem of a two‐dimensional binary gaseous mixture slit flow is investigated on the basis of numerical calculations of the linearized kinetic model proposed by McCormack [Phys. Fluids 16, 2095 (1973)]. The mass flow rate and the field flow of both components are calculated for several Knudsen numbers between 10 and 0.1. Kinetic coefficients satisfying Onsager’s reciprocity relations are found.
