cfx post- two phase flow- particle size distribution
hello all,
i am doing two phase flow steady state simulation (spray drying process) in cfx. my questions are 1) How to see the data of each single particle like moisture content , residence time ,velocity, temperature..etc..in cfx post 2)and also i would like to plot the size distribution of particles after drying process in cfx post..how can i do that..? please help me...if any one knows thanks hari |
Have a look at the CFX tutorials. There is some which do particle tracking so they will give some ideas on how to post process them.

actually i am doing simulation in cfx with a 9 degree section of my full geometry. 1)firstly i have full doubt about that how to check whether we got proper results after simulation ? 2) is it necessary to perform grid independence test..? because i have done some basic steady state simulation with 25000, 45000, 65000,90000 elements mesh..i have compared the velocity profile at particular location(line in radial direction) which shows agree with some % of error..but when i used fine mesh its not able to get converged and some times it displaying wall has been placed at outlet boundary so my question is that should i go for fine mesh or any coarser mesh also fine to perform my simulation..how to choose mesh size? 3) what it means if domain imbalance comes as negative ? and also can u please suggest me if possible the tutorial that which has covered that particle tracking in post process...? |
1. This series of FAQs concentrates on inaccuracies, but the discussion will be of use: http://www.cfd-online.com/Wiki/Ansys..._inaccurate.3F
2. It is common to have problems with convergence in finer meshes. If you have already shown that your answer is good within an acceptable accuracy then you should be OK. 3. Negative/positive just means there is a +/- mass/momentum/heat imbalance across the domain. |
