MICRO-EFFECTS ON CONTINUOUS-INJECTION HEAT-CONDUCTION CALORIMETRY

A localized-constant model involving two capacities reliably describes two injection calorimeters: a mass-variation calorimeter and a consta nt-volume calorimeter (TAM 2277 by Thermometric). The model distinguis hes the place and the types of dissipation, and its parameters depend on the rates and on the heat capacities of the liquids. IP the case of the TAM 2277 calorimeter, the dependence between the detected heat of mixing;md the injection rate is revealed. The proposed model permits the inclusion of perturbations on the baseline originating from the te mperature variation of the thermostat.
