<p>Hi ZJ,</p>
<p><br>
</p>
<p>rho = p01 = rho</p>
<p>mu = p02 (or, if p02 < 0, then mu = 1/| p02 | )</p>
<p><br>
</p>
<p>and your Reynolds number will be </p>
<p><br>
</p>
<p> Re_D = rho Ubar / (D mu)</p>
<p><br>
</p>
<p>How this translates into shear Re depends on the Reynolds</p>
<p>number you are running. An approximate formula: </p>
<p><br>
</p>
<p>Re_ô = 0.123 Re_D^ 0.875<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>May I know for shear Reynolds number (Re_t) equals to 361, whether setting p02 VISCOS in rea file to be -11700 and the pipe radius equals to 1 in the mesh part is correct. </div>
<div><br>
