Hey everyone,
Another post to get some explainations on my case ! When I track small particles using Runge-Kutta or Trapeze scheme, I get all my particles incomplete! But, when I try with implicit or combination of implicit and Runge-Kutta it works (no particle is incomplete) Any explanation, please ? Thanks Souria |

Hi souma,
i didn't understand well your question because i m beginner in that,but i guess that you can help me if you don't mind .i'm student in second year master degree ,i use fluent.16 for simulation of fluidized bed uses the pomace like particles (without combustion or any chemical reaction ),i m trying to understund at first the models that fluent use.and i think that i need the udf for determine the combustible (pomace)characteristics,someone told me that i will use ranj kutta ,can you help me to write this program please or give me some ideas to write it thank you for any help |

Hi souria ,
thanks for your response yes i m trying to understand because i m beginner in this,sorry my english is so bad if you don't mind i will ask you again in my final projecti should I have to determine the point of optimal fluidization operation (the necessary air speed and particles), I work on a biomass boiler, I draw the geometry and I did the mesh (there is not chemical reactions or combustion in the beginning, there is just fluidization), but regarding the models I found difficulties ,there are several choices and more bars, I am dispersed ,if you can help me I will be appreciated souria, guide me please. |
