This paper studies the relationship between drag coefficient of particle clusters and the particle Reynolds number during settling process using Lattice Boltzmann Method. The interaction among each particle in the cluster was briefly discussed. This simulation calculated the drag coefficient of five-particle cluster with different Reynolds numbers. The drag coefficients for the particles at different...
The lattice Boltzmann method is increasingly important in facilitating large-scale fluid dynamics simulations. To date, these simulations have been built on discretized velocity models of up to 27 neighbors. Recent work has shown that higher order approximations of the continuum Boltzmann equation enable not only recovery of the Navier-Stokes hydro-dynamics, but also simulations for a wider range...
An early wildfire detection is essential in order to assess an effective response to emergencies and damages. In this paper, we propose a low-cost approach based on image processing and computational intelligence techniques, capable to adapt and identify wildfire smoke from heterogeneous sequences taken from a long distance. Since the collection of frame sequences can be difficult and expensive, we...
