Solid body calorimeter with one automatically regulated adiabatic jacket: Influence thermal and operated parameters on heat equivalent

Abstract

The general model of solid body calorimeters (uniform solid body of arbitrary form) with one automatically operated adiabatic jacket was considered for the first time. The problem was to understand if there was general relationship between heat and temperature rise when calorimeter had essential temperature gradients and surrounded one automatically operated adiabatic jacket.It was shown that it was linear relation and proportionality coefficient (heat equivalent of calorimeter) did not depend on form of temperature dependence in main period but depend on (i) location of heat source; (ii) thermometer location; (iii) heat exchanging conditions and parameters of regulation. Experimental checking of theoretical considerations showed that under the same heat exchanging conditions and parameters of regulation, the heat equivalent of calorimeter for thermometer located on calorimeter surface differed from heat equivalent of calorimeter for thermometer located at radius r = 0.5 R by 0.2%.
