how to write heat and mass transfer equations in specify control volume for one dimensional(only height direction) in fixed bed combustion.
Dear Isuru Sajith :
Maybe I can help you with the Heat Transfer part if you provide a descriptive diagram of the apparatus showing you CV
Regards !
Dear Isuru Sajith Rathnayaka :
I have some questions :
1. The "primary air" stream you drew entering to the reactor from the bottom.
How is it produced ? I mean, what is the mechanism which puts this air in motion ? And, What is the Temperature of this air stream ?
2. What is the average temperature of the Albizia Lebbeck Sawdust ? Are you considering a uniform temperature along the z-direction ?
3. Does your reactor have some kind of insulation (since your drawing does n't show layers of different materials on the walls of the reactor) ?
4. Can you give a little more detail on how the combustion flame is in contact with the sawdust in the upper part?
I mean, is the flame, or combustion gases, in direct contact with the sawdust ? or you have any kind of contact interfase/heat transfer interfase ? a Heat exchanger ? to avoid getting the sawdust mass in direct contact with the combustion gases ...
Best Regards !
