Data on the velocity slip and temperature jump coefficients

Modeling microfluidics it is necessary to calculate gas flows through micropumps, microvalves and other elements. A heat transfer through a gas in microscales must be also known for modeling of microsystems. Since the size of microsystems is close to the molecular mean free path, the gas rarefaction must be taken into account. If the Knudsen number is moderately small then gas flows and heat transfer can be calculated applying the continuum mechanics equations with the velocity slip and temperature jump boundary conditions. In the present work, a critical review of the theoretical results on the slip and jump coefficients and their recommended data are given.
