Abstract
The purpose of this study is to analyze the capillary performance of triangular microgrooves. The influences of several major of parameters on the capillary performance (wetted axial length) of triangular microgrooves are discussed theoretically. One dimensional, nonlinear and contact angle possessed differential and algebraic equations are both used for the theoretical analyses of triangular microgrooves. In this study, the curvature radius, cross section area, and distribution of pressure and velocity of working fluid in microgrooves are considered. Besides, the mutual effects among inertial force, body force, capillary force, and friction force are also discussed. The significance of contact angle and hydraulic diameter to the prediction of capillary performance for microgrooves are both demonstrated by the proposed algebraic solutions.
