چکیده
Air bubbles in working oil influence stiffness and efficiency of hydraulic systems, thus it is important for technical issues to eliminate the air bubbles actively from the hydraulic oil. Bubble eliminator is a device that removes air bubbles by using a swirling flow. In this paper, we investigate flow behavior in the bubble eliminator by means of laboratory experiments with a transparent bubble eliminator and numerical analysis. We especially focus on the diameter of vent port and analyze the relation between the parameter and removal performance of bubbles. The validity of numerical simulation is verified by comparing the results of the numerical simulation with flow patterns obtained from image photos of the experimental flow visualization. Moreover, we evaluate the optimal dimension of the diameter of the vent port from numerical analysis.
