Dear Foamers,
I am struggling to find a way through which I could calculate Second order velocity structure function: ![F_2(\mathbf{x}, \Delta c)=\frac{1}{6} \sum_{i=1}^3\left[\left\|\mathbf{u}(\mathbf{x})-\mathbf{u}\left(\mathbf{x}+\Delta x_i \mathbf{e}_i\right)\right\|^2+\left\|\mathbf{u}(\mathbf{x})-\mathbf{u}\left(\mathbf{x}-\Delta x_i \mathbf{e}_i\right)\right\|^2\right]\left(\frac{\Delta c}{\Delta x_i}\right)^{2 / 3}](/Forums/vbLatex/img/f60dd6c2a3c52e3eea4e3e8de75ce4e8-1.gif "F_2(\mathbf{x}, \Delta c)=\frac{1}{6} \sum_{i=1}^3\left[\left\|\mathbf{u}(\mathbf{x})-\mathbf{u}\left(\mathbf{x}+\Delta x_i \mathbf{e}_i\right)\right\|^2+\left\|\mathbf{u}(\mathbf{x})-\mathbf{u}\left(\mathbf{x}-\Delta x_i \mathbf{e}_i\right)\right\|^2\right]\left(\frac{\Delta c}{\Delta x_i}\right)^{2 / 3}") I dont have any idea how to implement for an unstructured grid Last edited by Mhmd; January 16, 2023 at 03:16. |
