Hello Friends,

I am looking to do simulation of Fuel injection in IC engine. Thereby I needed to understand the similar case setup. I looked at the Spray dryer tutorial in CFX. I am not able to figure out that why there exist a negative reference state enthalpy settings. What is the logic behind it .

PS:I would be glad to know how mathematically this number obtained.

thank in advance for your response

Best Greetings
