Webwhere T ¯ is a second order symmetric tensor and × is the vectorial product. Once I integrated by part I want to use the divergence theorem to obtain a surface integral. It works very well in cartesian coordinates but I cannot manage to do it properly in cylindrical. ∇ ⋅ T ¯ = [ 1 ρ ∂ ∂ ρ ( ρ T ρ ρ) + 1 ρ ∂ T θ ρ ∂ θ ... WebFeb 17, 2024 · 1 Answer. Sorted by: 1. The rate of change of density ρ for each individual fluid particle is the time derivative of ρ in Lagrangian frame. Since the velocity field is given in Eulerian variables, this corresponds to the material derivative of ρ which is given by. D ρ D t = ∂ ρ ∂ t + u ⋅ ∇ ρ.
