This simulation explores a two-phase flow scenario where water enters a cavity initially filled with air at t=0, leading to the interaction between air and water. The full cavity is characterized by a water volume fraction of zero until water begins to flow in. This model examines the dynamics of air ingress as water fills the space, analyzing the subsequent changes in pressure, flow patterns, and phase interactions within the cavity. Understanding this process is critical for various engineering applications, including fluid management and environmental studies.
