Which of these terms corresponds to the cross stresses?(a) \(\rho\overline{u_i^{‘}\overline{u_j}}\)(b) \(\rho\overline{\overline{u_i}u_j^{‘}}\)(c) \(\rho\overline{\overline{u_i}u_j^{‘}} + \rho\overline{u_i^{‘}\overline{u_j}}\)(d) \(\rho\overline{\overline{u_i}u_j^{‘}}\, – \rho\overline{u_i^{‘}\overline{u_j}}\)I got this question during an internship interview.Question is taken from Turbulence Modelling topic in section Turbulence Modelling of Computational Fluid Dynamics |
