This tutorial model demonstrates some of the phenomena that occur when particles move through a turbulent channel flow. New Benchmark Model: Particle Dispersion in a Turbulent Channel Flow Alternatively, use the Thermal Re-Emission wall condition to model molecules that get adsorbed at the boundary and then immediately reemitted into the domain with different speeds based on the surface temperature.įrom left to right: Hexapolar grids containing two, five, and ten rings of points. Use the Thermal velocity distribution, available with the Inlet feature, to sample released particle speeds from the distribution. Two variants of this feature are available. Unlike other available particle-wall interactions, such as the diffuse or specular reflection, the new Thermal Re-Emission boundary condition samples the particle speed from a distribution, not just the direction of the velocity vector.

You can now release particles or reinitialize particle velocity at a boundary by sampling their speeds from a thermal distribution based on wall temperature.

The new settings for periodic electric and magnetic forces are more compatible with such general periodic fields.Īpplication Library path: Plasma_Module/Capacitively_Coupled_Plasmas/ccp_ion_energy_distribution_function Thermal Distribution of Particle Velocities from Boundaries Above is the potential from the tutorial CCP Ion Energy Distribution Function, which requires the Plasma Module, and a time harmonic potential for comparison. In plasma simulations, the electric potential is often periodic, but not time harmonic.
