In an axial flow machine, fluids flow condition, that is flow pattern in a rotating flow passage changes its form and magnitude by the hydraulic resistance to the fluid flow in flow passage. Effect of centrifugal force becomes stronger with the increase of hydraulic resistance, and the flow rate becomes smaller. And, in the comparison of fluids flow condition among different axial flow machines...

In the turbulence that takes place in rotating fluids, the symmetry assumptions of the theory of fully developed turbulence may not hold, in particular, isotropy must be relaxed to axial symmetry. This symmetry reduction leads one to consider the most general axisymmetric viscosity tensor for a Newtonian fluid, which can be obtained by group theory methods. This tensor generates new turbulent e...
