Lattice - Boltzmann Lighting Models
In this chapter, we present a GPU-based implementation of a photon transport model that is particularly effective in global illumination of participating media, including atmospheric geometry such as clouds, smoke, and haze, as well as densely placed, translucent surfaces. The model provides the “perfect” GPU application in the sense that the kernel code can be structured to minimize control fl...
متن کاملLattice-Boltzmann-based two-phase thermal model for simulating phase change.
A lattice Boltzmann (LB) method is presented for solving the energy conservation equation in two phases when the phase change effects are included in the model. This approach employs multiple distribution functions, one for a pseudotemperature scalar variable and the rest for the various species. A nonideal equation of state (EOS) is introduced by using a pseudopotential LB model. The evolution...
متن کاملLattice Boltzmann Models for Complex Fluids
We present various Lattice Boltzmann Models which reproduce the effects of rough walls, shear thinning and granular flow. We examine the boundary layers generated by the roughness of the walls. Shear thinning produces plug flow with a sharp density contrast at the boundaries. Density waves are spontaneously generated when the viscosity has a nonlinear dependence on density which characterizes g...
متن کاملLattice Boltzmann models for nonequilibrium gas flows.
Due to its computational efficiency, the kinetic-based lattice Boltzmann method has recently been used to model nonequilibrium gas dynamics. With appropriate boundary conditions, lattice Boltzmann models have been able to capture both velocity slip and temperature jump at a solid surface. To enable these models to simulate flows in the transition regime, both high-order and modified lattice Bol...
