Fluctuation-dissipation theorems and transport coefficients of the gases, liquids and nanofluids

In present paper a problem of the determination and calculation of transport coefficients is discussed. Gases, liquids, dispersed fluid including nanofluids are considered. The special section deals with the transport processes in fluids under confined conditions. The fluctuation dissipation theorems for transport coefficients of the turbulent fluid are formulated. It was shown that in all cases the transport coefficients are determined by the fluctuation-dissipation theorems. In according with these theorems the transport coefficients are the integrals of the correlation functions of the microfluctuations of the corresponding dynamical variables. The structure of the viscosity coefficient of all media mentioned above is analysed in detail. In the last part of the paper these viscosity coefficients are calculated by the molecular dynamics method.
