摘要
The change of flow state in the flow field significantly impacts the operational performance of fluid machinery equipment such as aircraft or underwater vehicles, among which transition and separation are essential links in a flow state change. Because the physical properties of water and air are very different, the transition and separation characteristics in water and air will change even for the same experimental object. Based on the general law of flow state change in the flow field, from the perspective of kinematics and dynamics and the difference in medium, the basic theoretical model of transition and separation is established via the employment of applied mathematics methods, the accuracy and applicability of the method are verified. The influence of water and air on the critical parameters of the flow state change in the flow field is analyzed, and the differences in transition and separation characteristics in different media are summarized. The research results could provide theoretical support to solve the water–air correlation study.
