Abstract:

GAlilean transformations between the absolute and moving frame impose a crypto-steady state relation between time derivations of a thermodynamic function in the absolute frame and their gradients in the moving frame. These crypto steady relationships are inherently contained within the Navier-Stokes Equations for the absolute and moving frames. The substantial total enthalpy derivative coupled with the substantial entropic energy derivative may be written solely in terms of the flow field of the moving frame. In the moving frame the relative total enthalpy, known as the rothalpy, yields a vanishing substantial derivative. Therefore, the substantial entropic energy derivative is uncoupled and explicit in the moving frames and may be used to obtain an uncoupled explicit substantial total enthalpy derivative.
