Hi nek users,
<div class=""><br class="">
</div>
<div class="">For u=U + u’ where U= mean streamwise velocity and u’= fluctuation of streamwise velocity</div>
<div class=""><br class="">
</div>
<div class="">I know how to calculate du/dx , du/dy and du/dz. But how can I calculate gradients of the
<i class="">fluctuation</i> of streamwise veloctity, i.e. du’/dx , du’/dy , du’/dz ?</div>
<div class=""><br class="">
</div>
<div class="">Thank you.</div>
