hot to simulate the reaction: SiCl4(g)+O2(g)-->SiO2(s)+2Cl2(g) in fluent,how to carry out it!

the reaction as following:

--------------------ĄŁ-ĄŁ-----------

-----> o

SiCl4+O2 -----> o SiO2 particle

-----> o ĄŁ ĄŁ

------------------------------------

Look in manual under surface reactions. Have a look at some of the tutorials.

thank your message, but the reaction takes place in gas phase, which is volumetic reaction not a surface reaction. the particls,sio2, generated in gas, the the particle deposits on the surface due to the thermophosis force. in fluent, what to do for the chemical reaction with particle model. in the side, there are some paper for mcvd, but how to carry out it?

OK, well I don't know your process, but here's how I normally approach such problems:

1) write down the governing equations, bcs for your problem

2) compare them with Fluent and its models

3) if same use inbuilt Fluent models

4) if different use udfs and/or uds scalars to transform Fluent so it solves eqns (1). In some cases, you can't transform Fluent to solve (1) due to Fluent's limitations, in that case you need to change your problem deifinition (1) or use another code.

So you're problem involves small particles/molecules of solid being formed in the gas phase and then transported to the wall?! Depending upon how much detail you want/need to model, I imagine you can transform his into a surface problem. To actually model the transport of material from the gas phase to the wall could be difficult in Fluent. Ask Fluent more about it.
