backflow temperature specification
Hi, dear Fluent users. I am currently modeling flame flashing-back from the exit of a channel. At the initial stage when the flame just propagates back into the channel, there is backflow at the outlet plane, which is very important to sustain the flame. So what I want to do is to specify the backflow temperature with the value at the exit plane, instead of the ambient temperature which is 293K, in my case. Thus, I need to call the outlet temperature to specify the backflow temperature in the UDF code. My question is how to "borrow" the temperature of outlet in the UDF for backflow? Has anyone of you come across the same problem or any idea about this problem?
