Question

TuteeHUB · Accepted Answer

$-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})$

TuteeHUB · Answer

$-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = \rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})$

TuteeHUB · Answer

$-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = \rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_j}+\frac{\partial U_j}{\partial x_i})$

TuteeHUB · Answer

$-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})$

TuteeHUB · Answer

$-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_j}+\frac{\partial U_j}{\partial x_i}) $

1.	Expand the Reynolds stress term \(-\rho \overline{u_{i}^{‘} u_{j}^{‘}}\) for the Spalart-Allmaras model.
A.	\(-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = \rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})\)
B.	\(-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = \rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_j}+\frac{\partial U_j}{\partial x_i})\)
C.	\(-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})\)
D.	\(-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_j}+\frac{\partial U_j}{\partial x_i}) \)
Answer» C. \(-\rho \overline{u_{i}^{‘} u_{j}^{‘}} = 2\rho \overline{v} f_{v1} (\frac{\partial U_i}{\partial x_i}+\frac{\partial U_j}{\partial x_j})\)
