viscosity theory

The internal relation between viscosity and thermal conductivity coefficient has been revealed based on Fourier thermal conductivity law and Newton viscosity law. The transport characteristic of viscous is pointed out according to exchanging-coupling theory and its application to industrial control is discussed.
