continuous and discrete phase coupling in fluids-HELP
 
hello all....

i need your guidance in a fundamental concept....
what is meant by "continuous and discrete phase coupling"?

i understand that the discrete phase uses euler-lagrangian eqns. to solve for the
particle trajectory.., but how should it be accounted for in a fluid flow consisting
of minute particles . how should the discrete phase of the particles as well as the continuous phase of the fluid be coupled together in a CFD simulation.. ( especially using Fluent 6.3).. i`m working on a project requiring such a simulation.
please share your knowledge and suggestions, including online material about this,( which is scarce) ... i`m quite short of time in this project.

thanks in advance:)

discrete phase / continuous phase coupling
 
Hi there,
take a look at this discussion

http://www.cfd-online.com/Forums/flu...el-fluent.html

A detailed ppt explainign the discrete phase modeling can be obtained from

http://www.bakker.org/dartmouth06/engs150/15-dpm.ppt

Hope it helps.
