DPM Heat and mass transfer.

prasadsai31 · September 23, 2014, 13:26

Hello,
I'm doing Spray drying simulation. Using DPM heat and mass transfer UDF Macros for the multi component drying. My model (I have done some changes) drying depends on particle mass fraction and droplet temperature. Initial fractions of droplet is known. After first time step particle will loose some water(drying), than how should I get the present particle mass fractions for calculations.

I dont really know if this is what you are asking for, but you can get prevous time properties by employing the sufix _M1. See http://www.cfd-online.com/Forums/flu...ep-macros.html for further info
