The adverse weather simulation is done with cameras climatic laboratory tests, also known as environmental chambers or chambers of accelerated environmental aging.

These laboratory equipment can predict the behavior of both materials and systems, as animals and plant species following exposure to various adverse weather conditions which can be displayed and the conditions under which their survival under climate critical.

This dissertation is concerned with the mathematical modelling of oil recovery by steam injection using analytical techniques.

An integral method for generating approximate solutions to the one and two- (three-) dimensional steam injection processes is presented. Due to the qualitatively different character of the problem the one- and two- (three-) dimensional cases are examined separately.

The applicability of the method for the determination of the rate of growth of the steam zone volume in one-dimensional systems is considered. An extensive study of the heat transfer in the surroundings and the hot liquid zone is carried out to complement the one-dimensional implementation of the technique. The resulting class of moving boundary problems and their methods of solution are discussed in detail. The results obtained are then combined with the integral technique to derive upper and lower bounds, asymptotic solutions and approximate solutions to the rate of growth of the steam zone. The important physical parameters are identified and their significance in the design of the process is outlined. In particular, the very important effect of heat transport in the surroundings and the hot liquid zone is fully accounted.
