Abstract
A new software platform based on the particle transport and Montecarlo techniques is described. The code, named FEMME, is a new portable environment that’s naturally integrated with the in house fluid dynamics RUNS code of CRS4 (KARALIS). This code permits to simulate physical problems associate to the fluid motion that depends on the lagrangian displacement of particles in the fluid. Pratically developed an hybrid algorithm particle-finite-volume to join the Reynolds averaged Navier Stokes equations and Montecarlo transport equations , to solve particular and complex fluid dynamics problem joined to reactive or turbulent flows. The first application carried out is concerned with the Rubbia’s Project 242. Other field of application may be related to combustion problems, to improvement of turbulence modeling, as well as to the transport of passive scalars in environmental and geophysical applications.
