Question

TuteeHUB · Accepted Answer

$\rho\overline{\overline{u_i}u_j^{‘}}\, – \rho\overline{u_i^{‘}\overline{u_j}}$

TuteeHUB · Answer

$\rho\overline{u_i^{‘}\overline{u_j}}$

TuteeHUB · Answer

$\rho\overline{\overline{u_i}u_j^{‘}}$

TuteeHUB · Answer

$\rho\overline{\overline{u_i}u_j^{‘}} + \rho\overline{u_i^{‘}\overline{u_j}}$

TuteeHUB · Answer

$\rho\overline{\overline{u_i}u_j^{‘}}\, – \rho\overline{u_i^{‘}\overline{u_j}}$
