متن کاملGlobal particle-in-cell simulations of microturbulence with kinetic electrons
The effects of nonadiabatic electrons on ion temperature gradient drift instabilities have been studied in global toroidal geometry using the gyrokinetic particle simulation approach. Compared to the nonlinear global simulations based on only the adiabatic response of the electrons, we have found that the cross-field ion heat transport is two to three times larger in the presence of trapped ele...
متن کاملFluid-Particle simulations with FreeFem++
We present here a method to simulate the motion of rigid particles in a Newtonian fluid. The rigid motion is enforced by penalizing the strain tensor on the rigid domain and the time discretization is performed using the method of characteristics. This leads to a generalized Stokes variational formulation on the whole domain which can easily be implemented from any Finite Element Stokes/Navier-...
متن کاملFluid Flow and Particle Deposition Simulations in the Human Nose
In this work, the aerodynamics and particle flow patterns in the human nose are simulated by Computational Fluid Dynamics (CFD). The simulations were carried out by use of Fluent, and the volume grid was generated by Tgrid. To be able to perform successful CFD-calculations of the nose, construction of a proper surface grid of the nasal cavity was mandatory. A high resolution CT-scan was the fir...
