Web9 apr 2024 · From the images, the particle positions, velocities, and accelerations were determined via the ‘Shake-The-Box’ (STB) Lagrangian particle tracking algorithm. With this approach, we could simultaneously track more than 300,000 particles and hence study the resulting turbulent structures in the Eulerian and Lagrangian frames while resolving the … Web8 nov 2024 · An application of Arbitrary Lagrangian-Eulerian (ALE) method is used to generate the cutting pattern shapes of membrane structures. The initial patterning panels are selected as the projection of three-dimensional (3D) membrane panels and are assumed as the reference configuration.
WebIn this article an arbitrary Lagrangian–Eulerian (ALE) formulation for modelling cavitation in elastohydrodynamic lubrication (EHL) is derived and applied to line contact geometry. The method is developed in order to locate the position of cavitation onset along the length of the contacting region which gives the transition from liquid to vapour in the fluid. http://www.me.sc.edu/research/jzuo/Contents/ALE/ALE_1.htm
WebThe arbitrary Lagrangian-Eulerian (ALE) is a finite element formulation in which the computational system is not a prior fixed in space (e.g. Eulerian-based finite element formulations) or attached to material (e.g. … WebThree different methods of simulation were performed. These methods are empirical blast method, arbitrary Lagrangian Eulerian (ALE) method, and coupling of Lagrangian and ALE method. Free field pressure history recorded from experimental test was compared with the first method.
