To show how the particle inertia affects the distribution of particles downstream in the channel, a Parametric Sweep is run over six different values of the Stokes number.
Particles of sufficiently high inertia tend to cluster close to the wall because of their ability to cross between different eddies in the flow. This example shows how inhomogeneous, isotropic turbulence in the wall region affects the particle motion. The CRW model perturbs the drag force on the particles in random directions based on the turbulent kinetic energy and turbulent dissipation rate of the fluid. To couple such a flow field to the particle tracing simulation and still account for turbulent dispersion, a continuous random walk (CRW) model is used. The fluid velocity is computed using a Reynolds-Averaged Navier-Stokes (RANS) model and, as a result, the individual eddies of the flow are not explicitly modeled. 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 For users of the Particle Tracing Module, COMSOL Multiphysics version 5.3 includes many new features, highlighted by the Periodic Condition and Rotating Frame features for particle tracing in sectors and rotating machinery, respectively. A range of inlet and outlet flow velocities was simulated to find the best balance between the velocity of the feed flow across the microsieve (V y) and the velocity of the fluid flowing through pores of 50 µm (V x). 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. A cross-flow microsieve (CFM) module was numerically simulated in 2D, with COMSOL 5.3. 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 with the Particle Tracing Module: the Charged Particle Tracing interface ( ), the Particle Tracing for Fluid Flow inte rface ( ), and the Mathematical Particle Tracing interface ( ), respectively. Above is the potential from the tutorial CCP Ion Energy Distribution Function, which requires the Plasma Module, and a time harmonic potential for comparison.
