( 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

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.
