This work studies the fluid dynamics of solids in splash zone fluidized bed furnaces, with focus set on back-mixing and entrainment order to enhance understanding prediction flow bottom region furnace. Experimental results show establishment a also for runs absence dense bed. A simple model assuming ballistic trajectories ejected is shown satisfactorily estimate rate. The flux non-backmixed sol...

In this work we investigate the transient solidification of a Lennard-Jones liquid using non-equilibrium molecular dynamics simulations and continuum heat transfer theory. The are performed in slab-shaped boxes, where cold thermostat placed at centre box drives liquid. Two well-defined solid fronts propagate outwards from towards ends until is completed. A phase change model that accounts for d...

The exact contact theory is an efficient alternative to the more general yet computationally expensive Finite Element Method for detailed study of elastostatic problems. For its application in conformal problems, needs be fed with influence coefficients (ICs) appropriate non-planar solids. An analytical approximation ICs solids was proposed a previous work, avoiding involved process generally n...
