kineticGasEvaporation

Does anyone have any experience modeling a liquid to gas evaporation phase change using icoReactingMultiPhaseInterFoam. I have not been able to get a gas phase, even though the temperatures are above Tactivate. Thanks!

Code:

(liquid to gas)
	{		
		type			kineticGasEvaporation;
		C			1.9;	
		alphaMin		0.0;	
		alphaMax		1.0;
		Tactivate		2000;	
		Mv			59.75;	
	}

Hi,mattms!
I am facing the same problem.
Has there been any progress since then?

Have you updated to OpenFoam v2006? I got it to work using these values:

Code:

(liquid to gas)
	{		
		type			kineticGasEvaporation;
		species 		vapor.gas;
		C			1;	
		Tactivate		3188;	
		isoAlpha		0.5;
	}
