International audience; This paper deals with the modeling of weakly rareed and dilute gas ows in micro channels by the continuum approach, valid for Knudsen numbers smaller than about 0.1. It particularly focuses on the modeling of the associated he

International audience; A parametric study of nitrogen flows in a 2D micro channel of 3 µm height and 1.5 mm long, heated at constant flux, is carried out for a wide range of inlet and outlet pressures (0.9

The effects of compressibility and velocity and thermal slips are studied by numerical simulations for an argon flow in isothermal or adiabatic micro channels of length 2,8 or 15 mm and height 28 µm, for Knudsen numbers between 0,001 and 0,1 and pre
