DPM-Source Code for Standard Vaporization Law
 
I have been going through the forum archives and it seems that there used to be a link to the standar laws' source codes.

Sadly, this link has been removed. Did anyone managed to save a copy or have access to the source codes.

Desperately need this to debug a UDF that I have wrote to control the vaporization particles in DPM.

Please help if you can.

A few years ago, our Fluent support engineer shared some details of the standard source code for volatilization. We have incorporated this into our own custom laws.

Perhaps you could talk to your support engineer. Or, if you had some specific question, I might be able to help.

Re: DPM-Source Code for Standard Vaporization Law
 
Thank you Allan. Let me describe specifically my question:

I have written an UDF to control the droplet saturation vapour pressure in an attempt to implement a droplet drying model through using the standard vaporization model.

The UDF works well until the final stages of vaporization (as the mass changes becomes smaller), the droplet mass suddenly drops to the 0%volatile as though there is a sudden vaporization.

I have arbitrarily set the boiling to very high such that the boiling model will not be activated. Double checking and collecting operating data from the UDF did not reveal any problem. I reckon if we can look at the vaporization law 'black box', we can find out what is the cause.

Hope you can offer your help.

If you want to give me your e-mail address, I could send you some generic info.

Hi Allan. I have been struggling with the devolatilization law for a long time. I planned to implement a standard single rate model so that I could development my own model base on those codes. However, I failed to code the standard devolatilization model.

At this moment, I have coded the single rate model, also considered the particle diameter and the heat transfer. I don't know how to deal with the source term correctly, although I can use the DPM_SOURCE macro, but the result is different from that computed by the default model.

Could you please give me some advise or share some information?

Thank you in advanced.
