<br clear="all">Hello, Paul,<br><br>Thank you for your answer for the same problem last month. <br><br>But I still could not figure out this issue. (Domain:6.4/2.0/3.2, Resolution: 12*8*12 elements with 8th order, turbulent Re_tau=178.12, Pr=0.71) ,<br>

<br><br>After a long time running (dimensionless time > 350 )<br><br> I compared the result , the velocity profile looks good.<br> <br>But the temperature is much higher than Kasagi's result. <br><br><br><br>I'm wondering whether the parameters above are correct ?<br>
<br><br> I attached the plot of mean velocity and mean temperature. <br><br>Thank you again<br> <br><br><br>-- <br>Zhicheng Wang<br><br>
