Study on Lateral Jetting Range During an Arc-Curved Jet Impacting Nonplanar Solid Surfaces

Abstract

This paper focuses on the lateral jetting commencing points associated with the peak pressure when an arc-curved jet impacts flat, concave, convex, and inclined solid surfaces, respectively. A theoretical method based on a shock wave background is used to establish models for these situations, which indicate that the critical radius for the initiation of lateral jetting is dependent on the combined actions of the jet velocity, surface shape, and surface angle. Arbitrary Lagrangian–Eulerian (ALE) formulations are then used to model the process of arc-curved jets impacting varied solid surfaces. The numeric simulation results are found to be in good agreement with the theoretical models.
