combustion of single particle enclosed in a box
 
Hello, I am trying to simulate the combustion of a single particle enclosed in a box using fluent. I assumed five faces whit velocity inlet and one whit pressure outlet. The particle is porous. I need see how it is consumed. is this possible? how I can do it? thanks

After doing several similar projects, I don't think Fluent is your best option. Fluent is good for fluid flow and keeping track of enthalpy, gas species, etc.

From the little that you have said, I'm assuming that you will need some detailed models to represent your particle combustion. If you want to implement these in Fluent, you will have to do them as UDF's which means you have to write the code using Fluent's structure and variables which is more time consuming than just doing it as a separate model.

What variables are you interested in? The effect of gas velocity, temperature, and composition on combustion rate? If you change these things as boundary conditions in Fluent, it won't be too exciting since the conditions in the box will likely remain essentially uniform.

Have you considered just writing your own stand-alone code or use something like Matlab or just Excel? Good Luck.

Hello Allan. I need to know the temperature of the particles and the composition. I want to use fluent to compare the results with fortran using a physical model known. thanks
