Dear all, I've cut seven cross-sections along the length(1 m for each) and plotted their velocity vectors colored by temperature (up/letf is cfx result, bottom/right fluent). We can see from the...

I have tried hybrid with a blend factor of 1.0, the residual of all equation remained high. The results seems not correct, so Ichanged the blend factor to 0.75. I have also tried changed the time...

To be honest, I am not sure the fluent results are entirely correct. But the fluent result seems more reasonalbe. Because thermal stratification is caused by different density, the thermal interface...
