Current wisdom provides that the basically thermal character of the gradual phase of a solar flare is a tertiary effect, resulting from the gradual release of energy from the ablated products of chromospheric evaporation. Our studies which quantitatively incorporate the measured bulk flows and the turbulent flows in a comprehensive flare energetics model tend to confirm this theory. The model is a boundary value problem which solves the one-dimensional energy equation semi-empirically for plasma density, utilizing continuous time-referenced electron temperatures, emission measures, and velocity measurements. Observed variations in enthalpy of the flaring plasma are equated to the energy sources and modeled loss mechanisms.
