Fluidization of 1204 spheres: simulation and experiment
In this paper we study the fluidization of 1204 spheres at Reynolds numbers in the thousands using the method of distributed Lagrange multipliers. The results of the simulation are compared with a real experiment. This is the first direct numerical simulation of a real fluidized bed at the finite Reynolds number encountered in the applications. The simulations are processed like real experiment...
متن کاملDirect Numerical Simulation of Fluidization of 1204 Spheres
One goal pursued there is to demonstrate that numerical experiments on fluidization can be processed in log-log plots for straight lines leading to power laws as did Richardson and Zaki 1954 for real experiments. As far as we know, we are the only group of researchers to carry out this program. There is no prior literature, in which power laws are obtained from numerical experiments. On the oth...
متن کاملHeat Transfer in a Column Packed With Spheres
The purpose of the study is to investigate average and local surface heat transfer coefficients in a cylinder packed with spheres. Here the term «local» applies to a single sphere within the bed. Averages are derived from the sixteen different spheres that were instrumented and distributed throughout the bed. The experimental technique consisted of introducing a step - wise change in the temper...
