results of CFD code in multiphase flow
 

Hello Everyone!
Here are the results of the code that I developed (pressure and temperature). This is to simulate the injection of steam into an reservoir oil . there are four injector wells in the 4 corners of the reservoir. the problem is that I do not understand why the temperature near the injection well, decreases relative to the temperature of the tank while I imposed a constant temperature in these wells. I also observed that although I inject steam, but it does not appear to vapor in the tank. What do you think of these results. RECOMMENDED what you give me?
