...Yu Lu; Ling Hong; Jun Jiang Purpose This study aims to propose a novel deep operator learning framework, the dual-channel Multi-Scale Attention Wavelet Neural Operator (dcMAWNO), specifically designed for high-fidelity modeling of steep transitions in nonlinear fluid flows, such as shock waves...

...J.I. Ramos Purpose The purpose of this paper is to determine both analytically and numerically the existence of smooth, cusped and sharp shock wave solutions to a one-dimensional model of microfluidic droplet ensembles, water flow in unsaturated flows, infiltration, etc., as functions...

... characterize the solution and that the existence of a shock wave requires that the (semi-positive) relaxation parameter be less than unity and the non-linearity parameter be less than two. It is also shown that negative values of the non-linearity parameter result in kinks with a single inflection point...

...Eric Goncalves Da Silva; Philippe Parnaudeau Purpose The purpose of this paper is to quantify the relative importance of the multiphase model for the simulation of a gas bubble impacted by a normal shock wave in water. Both the free-field case and the collapse near a wall are investigated...

..., and results in a second‐order accurate scheme. A shock tube study was carried out to examine the interaction of a normal shock wave with a thin layer of porous, incompressible cellular ceramic foam. Particular attention was paid to the transmitted and reflected flow fields. The numerical model was used...

...G. Ben‐Dor; A. Levy; S. Sorek Presents a numerical solution to the Riemann problem inside a porous material using a TVD‐ based computer code which was developed during the investigation of the head‐on collision of planar shock waves with rigid porous materials. The numerical solution revealed...

...J. Vuillon; D. Zeitoun High‐power chemical lasers operating in high repetitive rate show a decrease of the output energy laser beam. In such lasers, the characteristic time which depends on the laser output is short in comparison with those related to the flow. Consequently, shock waves, acoustic...
