内容記述 | Introducing the concept of the overall specific heat, a basic equation for an unsteady heat conduction accompanied by an endothermic solid reaction was reduced to the form of an ordinary unsteady heat conduction equation with variable thermal properties. For crystal transformation and thermal decomposition on which a mass transfer rate has only a little and limited effect, the method of modelling the relation between the overall specific heat and temperature was deduced theoretically based on the simplified intrinsic reaction kinetics. A hot wire method was discussed to avoid appreciable errors caused by an end effect and a thermal-contact resistance and to measure the thermal conductivities of a reactant and a product solid at elevated temperatures. By applying the principles of a differential thermal analysis, a new measurement method was developed to qualify the thermal conductivity with reaction. It was shown from the results of the measurements that the temporary disorder or disintegration of a crystal lattice caused intrinsically by the reaction had a controlling effect on the thermal conductivity with reaction and then that the thermal conductivity with reaction had a smaller value than those in the non-reacting states. Taking account of the results from the above measurements and from the precise evaluations of thermal properties, the numerical solutions of the basic equation were presented not only for an one-stage endothermic solid reaction but also for a two-or a multi-stage reaction, and the powerful applicabilities of the overall specific heat and the thermal conductivity with reaction to the engineering problems were demonstrated experimentally. | |||||
