Journal ArticleDOI
TL;DR: In this article, a local radial basis function-based differential quadrature (LRQ) method is proposed, which discretizes any derivative at a knot by a weighted linear sum of functional values at its neighbouring knots, which may be distributed randomly.

Journal ArticleDOI
TL;DR: It is found that the original ghost fluid method (GFM) does not work consistently and efficiently using isentropic fix when applied to a strong shock impacting on a material interface, and a modified GFM is proposed and developed for greater robustness and consistency.

Journal ArticleDOI
TL;DR: The nonlinear evolution of gas bubbles in the vicinity of a free surface is investigated numerically in this paper, where the flow is assumed to be potential and a boundaryintegral method is used to solve the Laplace equation for the velocity potential.

Journal ArticleDOI
TL;DR: Wang et al. as discussed by the authors presented a 3D model of collapsing bubble with jet formation and impact, where strong instabilities of the jetting process, impact, and toroidal bubble rebound are dampened by a new smoothing scheme based on least squares, thus enabling a smooth transition from a singly connected bubble to a doubly connected toroid bubble.

Journal ArticleDOI
TL;DR: In this paper, a hybrid approach combining the conventional finite difference (FD) scheme and the mesh-free least square-based finite difference method (MLSFD) was proposed to simulate the two-dimensional steady and unsteady incompressible flows.

TL;DR: The differential quadrature method (DQM) as discussed by the authors is a numerical solution technique for initial and/or boundary problems, which was developed by the late Richard Bellman and his associates in the early 70s.
Abstract: The differential quadrature method is a numerical solution technique for initial and/or boundary problems. It was developed by the late Richard Bellman and his associates in the early 70s and, since then, the technique has been successfully employed in a variety of problems in engineering and physical sciences. The method has been projected by its proponents as a potential alternative to the conventional numerical solution techniques such as the finite difference and finite element methods. This paper presents a state-of-the-art review of the differential quadrature method, which should be of general interest to the computational mechanics community.

Journal ArticleDOI
TL;DR: A new numerical method for improving the mass conservation properties of the level set method when the interface is passively advected in a flow field that compares favorably with volume of fluid methods in the conservation of mass and purely Lagrangian schemes for interface resolution.

Journal ArticleDOI
TL;DR: In this article, a review of the recent progress in flapping wing aerodynamics and aeroelasticity is presented, where it is realized that a variation of the Reynolds number (wing sizing, flapping frequency, etc.) leads to a change in the leading edge vortex (LEV) and spanwise flow structures, which impacts the aerodynamic force generation.

TL;DR: This review paper identifies a novel classification of flying drones that ranges from unmanned air vehicles to smart dusts at both ends of this spectrum, with their new defined applications.
