Calcuation of shear stress in streamlines at inlet
Dear CFD users,
I have a question about how to calculate shear stresses in each streamline in Ansys CFX-post. Streamlines starting from 100 grid points at the inlet are considered. Each red blood cell is assumed to pass along the streamline. According to the method proposed by Bludszuweit, scalar stress values can be calculated as follows: scarlar shear stress = [1/3(tau_ii*tau_ii + tau_jj*tau_jj + tau_kk*tau_kk) - 1/3(tau_ii*tau_jj + tau_jj*tau_kk + tau_kk*tau_ii) + (tau_ij*tau_ij + tau_jk*tau_jk + tau_ki*tau_ki)]^(1/2) I really appeciate your help if you could give me a guide/direction. Regards, Stefano |
