Abstract

Many structures employed in various branches of engineering operate under conditions of strong, often extreme, thermal effects. The general tendency has been the extensive use of heat-loaded engineering objects and the high intensity of heat regimes. At the same time it has been necessary to increase the reliability and service life of goods, whilst reducing the specific consumption of materials. Investigating the processes of heat transfer and providing acceptable heat conditions also occupy an important place in the design and development of production methods related to the heating and cooling of materials as, for example, in continuous steel casting or the different techniques of metal thermal treatment, in glassmaking, foundry work, high-temperature crystal growing out of melt, etc. The non-stationary state and non-linearity (considerable, at times) of heat transfer phenomena can be referred to as the special features of heat conditions of modern heat-loaded structures and production methods. These considerably reduce the possibility of using many traditional design-and-theoretical and experimental methods. So it became necessary to develop new approaches to thermophysical and heat engineering studies. Amongst them are methods based on a solution of inverse problems, in which it is required, by measurements of the system or process state, to specify one or several characteristics causing this state (in other words, to find not causal-sequential, as in direct problems, but rather sequential-causal quantitative relations).
