A fluid dynamic algorithm based on smoothed particle hydrodynamics (SPH) is proposed for coordination of a team of unmanned aerial vehicles (UAVs) in a wireless sensor network. SPH is a Lagrangian particle method typically used to model compressible and quasi-incompressible fluid flows. In this study, SPH is used to develop a decentralized controller for a swarm of fixed-wing UAVs, which move in 3-D...
Appropriate dealing with boundary conditions is very important for SPH. Current boundary treatment methods like boundary force method, ghost particle method and virtual boundary layer method, when dealing with complex boundaries, they will have to compute much on putting external particles. For resolving this problem, we propose a new method assuming part of boundary surface instead of external particles,...
Two-phase flow problems are presented using the method of smoothed particle hydrodynamics (SPH). The combination of meshless and lagrangian nature inherent in the SPH method offers the advantages in treating large deformations, large inhomogeneities and tracing interfaces in the two-phase flow process. Two cases are solved using a SPH code developed at ACES. It is found that major physics of the two-phase...
