 September 24, 2008, 04:52 DPM concentration of each fraction #1 JFeg Guest   Posts: n/a Hello. How to dislay DPM concentration of each fraction ? In Fluent exists only concentration of all fractions together. Thanks for advice, JFeg.

 September 25, 2008, 03:00 Re: DPM concentration of each fraction #3 JFeg Guest   Posts: n/a Sorry, inaccuracy in translation.. I solve a DPM particles with vary diameter (1mm, 0.5mm, etc.). There are no valotaile or char fraction. Contours of "DPM Concentration" displays concentraion of all diametres of particles together. So, how to display DPM Concentration contours of certain diameter (for eample diameter 1mm OR 0.5mm..)? Thanks, JFeg.

 September 25, 2008, 13:33 Re: DPM concentration of each fraction #4 Allan Walsh Guest   Posts: n/a A couple of options come to mind to do this. You could plot the particle trajectories and color them by particle diameter to see the effect of diameter on their fate. Or, you could break your particles down into different injections. Each injection would have a certain diameter or diameter range. Once your fluid phase has been solved, run the DPM calculations for each diameter class and then plot out the DPM concentrations. Probably lots of other ways to do this.

 September 26, 2008, 12:32 Re: DPM concentration of each fraction #6 Allan Walsh Guest   Posts: n/a It may be possible to do a UDF. You might want to look at some of the questions and comments on UDFs from users of this site. Based on my experience, you would want to budget about a week to set up your system to run UDFs and learn how they work. Then, probably another week to write and test your UDF. So, it depends how you want to spend your time.
