We exploit a lesser-known connection between the (temporal) Reynolds transport theorem, Reynolds averaging and the Liouville equation for the flow of a conserved quantity, to derive new spatial and parametric forms of these theorems and associated evolution operators, which provide maps between different domains (in various spaces) associated with a conserved quantity in a vector or tensor field. First, for a time-independent continuous flow field described by Eulerian velocity and position… CONTINUE READING
