I am developing a code clacul modeling of non-isothermal multiphase flow in porous media. the problem is when I run the calculations, the results are not satisfactory. the problem is the injection of steam into an oil reservoir by four injection wells in the 4 corner of the tank and a producer well in the middle of the reservoir. in the results, no gaz phase appears in the tank, the temperature remains constant and equal the initial temperature of the reservoir, near the injection well the temperature is very low compared to the initial temperature of the tank while I impose a temperature equal at injection temperatures. So I do not understand these anomalies, I want you to help me. If someone has already experience these kinds of problems. what are the possible causes? Any line of thought would be welcome.
Thank you all
