Abstract
Introduction. The publication contains a description and results of a series of fire tests of a model of a "glass in a glass" oil product tank, obtained inter alia using the method of contact temperature measurement. The paper presents the formulation of the problem of experimental research, the conditions and methods for their implementation, a description of the instrumental base and the results obtained. The aims and goals. An experimental study is carried out to assess the effect of heat loads of a fire on the body of the protective wall in the event of a fire in the main tank as well as for further use of the obtained empirical dependences of the temperature of the body of the protective wall on the heating time for carrying out the verification procedure of the mathematical model for its adequacy to the investigated physical process. Methodology. Experimental research method, contact method of temperature measurement, observation, analysis, generalization. The results of the study. The paper presents the results of experimental studies on the basis of which empirical dependences were obtained for calculating the change in the temperature values of the protective wall model depending on the time of its heating. Fire tests made it possible to establish the general thermal state of the "main reservoir with oil product – protective wall" system. The contribution of the influence of different speeds of wind flows on the heating of the protective wall of the reservoir is determined. Conclusion. The data obtained in the experiments will be used for the numerical assessment of the stress-strain state of the steel shell of the tank protective wall in case of fire in the main tank, which is necessary for the design of fire-fighting systems for water sprinkling and foam fire extinguishing on the protective wall of the tank of the "glass in glass" type. Key words: protective wall, model, oil product, fire tests, fire, tank, stand, thermocouple, experiment.
