A Lagrangian radial basis function-based particle hydrodynamics method (RBFPH) is proposed. In RBFPH method, the differential quadrature technique is combined with radial basis function (RBF) to obtain the meshless high-dimensional derivative approximations for randomly distributed particles; a particular solution of RBF is chosen to ensure the positive definite of the interpolating matrix. Like the conventional RBF, RBFPH has the advantages of simple form, isotropy and high accuracy, and is suitable for numerical calculation. Moreover, all particles in RBFPH can move with the fluid, so RBFPH may conveniently compute complex flows with the moving boundary. A series of numerical examples are conducted to test the accuracy of RBFPH, and the results show the RBFPH has second-order convergence, which shows its great advantage in terms of accuracy. The RBFPH is validated by its application to the simulations of Taylor-Green flow, lid driven shear cavity flows, stretching of a free-surface circular fluid patch and flows around a cylinder. Excellent agreements with analytical solutions and reference results indicate that the proposed method has a promising application in simulating viscous flows with the moving boundary, large deformation, and free surface.

“…Among the many potential numerical methods, the mesh‐free method, smoothed particle hydrodynamics (SPH), is widely used for water flows with large surface deformation (Yang et al., 2014; Zheng et al., 2009) and large deformation simulations in granular flow (An et al., 2016; W. Chen & Qiu, 2012; Huang & Liu, 2020; Minatti & Paris, 2015; Peng et al., 2015). Over the years, SPH has also been widely used in simulating soil failure deformation, granular media flow, and soil‐water coupling.…”

Large-scale landslides near restricted water bodies, such as lakes, dammed reservoirs, and mountain rivers, may generate huge surge waves that in turn cause casualties and building damage. For example, a catastrophic rockslide, with a large volume of approximately 3 × 10 8 m 3 , slipped and fell into the Vajont reservoir in Italy in 1963. The resultant surge wave overtopped the Vajont dam causing the death of nearly two thousand people (Panizzo et al., 2005). This type of disaster chain involves complex multi-physical and multiscale problems, including landslide deformation, free-surface capture, multiphase coupling, and strong three-dimensional (3D) structural evolution.Numerous experimental studies have been conducted using indoor water channels. Generally, according to the type of sliding mass, these studies can be divided into two categories such as rigid-body models (Ataie-Ashtiani

“…[7][8][9][10] Moreover, the strength of hydrate reservoir will further decrease with the decomposition of NGH, which would result in the slip of hydrate sediments to the mining center and subsidence of the seabed, especially for the NGH production on the subsea slopes, and could even trigger geological disasters, such as submarine landslide and tsunami. 1,[11][12][13][14][15][16][17] Therefore, it is of great significance to well understand the mechanical properties of NGH sediments for the safe and sustainable exploitation of NGH.…”
