A formalism is presented for interpreting convective and viscous energy fluxes derived from experimental data and for correcting for them in the interpretation of measurements of the conductive heat flux. The corrections are shown to be significant in two JET pulses, suggesting that they should be taken into account in the experimental determination of thermal diffusivity in strongly rotating tokamak plasmas. A supplementary theory for ion and impurity particle fluxes, which retains ambipolarity in the presence of large anomalous electron fluxes, is presented. A theory, based upon gyroviscosity (the basis for which remains controversial), for the radial flux of toroidal momentum is presented and is shown to be in reasonable agreement with experiment for two JET pulses.
