Spatial averaging is suitable for ____________(a) homogeneous turbulent flows(b) unsteady turbulent flows(c) turbulent boundary layer flows(d) mixing flowsThis question was posed to me in examination.The query is from Turbulence Modelling topic in division Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct option is (a) homogeneous turbulent flows The best I can explain: Spatial averaging finds the average of a quantity BASED on a spatial interval or volume. It is suitable for homogeneous turbulent flows. In homogeneous flows, the PROPERTIES are invariant under the arbitrary TRANSLATION of the coordinate AXES.
