Abstract

Contact angle hysteresis has an important impact on liquid bridges between sphere particles. The paper studies the dynamic contact angles effect on capillary and viscous forces of liquid bridges, calculation results indicate that its effects on capillary force are significant; however, it has little effect on viscous force. Through the mathematical method the capillary force can be expressed as the function of contact angle and filling angle. By fixing the contact angle, changes in the capillary force during the wetting and drying processes can be assessed by analyzing the derived function of such function with regard to the filling angle. By fixing the filling angle, changes in the capillary force in the pinning process can be analyzed using the derived function and the contact angle.
