Abstract
Friction factor coefficients for liquid flow in a rectangular microgroove c oupled with the vapor flow in a vapor channel of a miniature two-phase devi ce were calculated using finite element analysis. The results show that the effect of the vapor-liquid frictional interaction on the liquid flow decre ases with curvature of the liquid-vapor interface. Shear stresses at the li quid-vapor interface are significantly nonuniform, decreasing towards the c enter of the liquid-vapor meniscus.
