Summary

For fully developed laminar flow, the conservation of mass and momentum equations reduce to the classic Poisson equation in terms of the liquid velocity. A finite difference solution was employed to determine the mean velocity, volumetric flow rate, and Poiseuille number as functions of the groove aspect ratio, groove-half angle, meniscus contact angle and imposed shear at the liquid-vapour interface. Application to helically grooved heat pipes is presented.
