Mathematical Models for Assessment the Thermal Radiation of a Fireball During Bleve

Intensive heating of oil and its products storage facilities can cause the BLEVE effect, with fireball formation. So that it is a fundamental problem to study the thermal effect of a fireball as accurately as possible and assess its consequences. This paper deals with the theoretical generalization and comparative analysis of three mathematical models for assessing fireball thermal radiation at BLEVE. The first model (MM1), proposed by M. W. Roberts, takes into account the time-dependent nature of the fireball thermal radiation. The second model (MM2) was given in the Appendix D of the project GOST 12.3.047-2012 of the National Standard of the Russian Federation. The third model (MM3) was given by Dhurandher, Kumar and Dhiman of the Indian Institute of Technology Roorkee. We will compare these three models by obtaining the following results: assumes that the bulk of the heat is emitted near the accident source. At the same time, at a long distance, thermal radiation intensity remains at a level similar to the levels MM2 and MM3. MM2 and MM3 do not have a fundamental difference in modeling of fireball parameters and calculating the thermal radiation intensity.
