Coordinated Heterogeneous UAVs for Trajectory Tracking and Irregular Payload Transportation Using Sliding Mode Control

Drones
Heterogeneous UAVs offer unique advantages in multi-agent systems due to their varying capabilities including (a) different payload capacities, (b) maneuverability, and (c) flight endurance. These properties made them particularly well suited for complex

Numerical simulation of transitional flows over high-speed vehicles using multiscale discrete velocity method

Kongqi donglixue xuebao
To address the challenge of predicting transitional flow characteristics of aerospace vehicles in rarefied gas environments at high altitudes, the multiscale discrete velocity method coupled with a steady implicit algorithm was employed to conduct ...

A DSMC-PIC coupling method for the Vlasov–Maxwell–Landau system

Journal of Computational Physics
We present a numerical framework for the simulation of collisional plasma dynamics, based on a coupling between Direct Simulation Monte Carlo (DSMC) and Particle-in-Cell (PIC) methods for the Vlasov–Maxwell–Landau system. The approach extends previously developed DSMC techniques for the homogeneous Landau equation to the fully inhomogeneous ...

Comprehensive Evaluation of the Massively Parallel Direct Simulation Monte Carlo Kernel “Stochastic Parallel Rarefied-Gas Time-Accurate Analyzer” in Rarefied Hypersonic Flows—Part A: Fundamentals

Computation
The Direct Simulation Monte Carlo (DSMC) method, introduced by Graeme Bird over five decades ago, has become a crucial statistical particle-based technique for simulating low-density gas flows.

A DSMC method for the space homogeneous multispecies Landau equation

CoRR
We present a Direct Simulation Monte Carlo (DSMC) method for the spatially homogeneous multispecies Landau-Fokker-Planck equation. The scheme is derived from a first-order approximation of the multispecies Boltzmann operator in the grazing collision limit and employs a regularized, easy-to-sample scattering kernel that removes the need for iterative ...
