In case of ignition and explosion of oil depot, it will cause a lot of human and financial losses because there is a large population around it. . Therefore, understanding how fire spread and fire modeling by using CFD software to predict the outcome of accidents and their potential effects are very helpful .This research examines for the first time dangerous and unexpected scenarios of explosion and ignition in oil sites using advanced Fluent and monitoring software in the country and seeks to preserve the life and financial assets of the areas around the oil depot.
Materials and Methods: This study is a descriptive-analytical research that was conducted in 1399 in one of the country's oil depots. Hurly formula and Ansys Fluent 15 software were used to estimate the energy rate from burning tanks, flame height and burning time of oil tanks. In this method, effective factors by dividing the case area into smaller elements and applying boundary conditions for boundary nodes were determined
Results: Energy and temperature due to burning materials in all tanks is about 139072.7 kW and 4000 degrees Kelvin. In case of ignition and explosion of oil, ambient temperature will be added about 70 degrees Celsius. Residential areas closer to the oil depot, including the grain depot, barracks and prison, Razkan Noo residential areas, parts of Banafsheh residential town and the railway area along this route will be more affected by this increase in temperature. The maximum burning time of the tank is six and a half hours and the minimum time was estimated at about 5 hours. The highest flame was calculated to be 70.60 meters.
Conclusion: The results of this study showed that if a fire occurs in the tanks. Different areas, including residential and industrial, are in the path of spreading pollution caused by fire. Due to the distance and severity of pollution produced, it can cause many financial and human losses. The results of this study showed that if a fire occurs in the tanks. Various areas are in the path of spreading pollution caused by fire, including residential and industrial, Due to the severity of pollution produced and the extent of areas involved it is predictable human and financial losses.
