To resolve frequent arguments on the form of the convective part of the thermal energy flux, the relevant definitions and equations are compiled. The relative importance of the different terms involved is shown for JET data. The choice of the "adiabatic source terms", p.div v or v.grad p, decides the form of the convective heat flux. Practical reasons usually favour the expression 3/2 kT nv.
