摘要
An analytical model of steady gaseous flows through rectangular microducts with second-order boundary conditions is proposed. It completes previous studies on flows in circular microtubes or between parallel plates found in the literature. The influence of the second-order terms and of the geometric parameters is analyzed. It is shown that the mass flow rate is underestimated when second-order terms are not taken into account and that these terms become more significant when the cross section of the microduct tends to a square cross section. Difficulties in obtaining exploitable experimental comparisons, due to problems in the determination of the Maxwell reflection coefficient sigma (v), are also discussed.
