Fire & Smoke in Building

September 11, 2003, 15:48

I would like to simulate the development of fire(temperature distribution) and smoke in a building by using Fluent in order to validate the fire safety system. Unfortunately, I can't find any function in Fluent to simulate fire and smoke. Can anyone tell me if there is any function to do this in Fluent and what are they ?

It looks like I could simply put a (constant) heat source and (constant) smoke source without any chemical reaction to simulate fire (temperature distribution) and smoke, and treat them as passive scalars except I need to include the thermal stratification in the model. Could you please give me any suggestion or comment on this ?

Thanks a million.

Cheers

you can write UDFs which supply time-varying heat sources and time-varying species sources to represent the energy and smoke released from a fire.

Hi all,

Can anyone provide a tutorial for smoke and fire simulation using ANSYS Fluent?

Please urgent reply

Fire is combustion, Smoke is soot, CO2, ...
Fluent can model these so you can model Fire and Smoke using fluent. So easy.

Thank u msaeedsadeghi, but i'm a new user of ANSYS fluent;
Is there any tutorials that can help?
