Momentum-Transport Hypothesis


Momentum-Transport Hypothesis : The hypothesis that momentum is conserved in turbulent eddy transfer. This hypothesis, together with that of the mixing length, leads to an expression for the variation of the shearing stress t with height dz dz ^ dz) where p. is the eddy viscosity and the mean horizontal wind. This hypothesis is to be compared with the vorticity-transport hypothesis, the respective results being identical only if the eddy viscosity is constant. N.B. Refer to source to verify equation(s)
