Description
Summary:In order to obtain the time to failure of adjacent tanks under multi-thermal radiation conditions, the thermal response of gasoline tanks under multi-thermal radiation was studied. The heat radiation values of the adjacent tanks under pool fire were calculated. The temperature distribution and the corresponding stress of the adjacent tank were studied with ANSYS-Workbench software under the influence of single heat radiation and multi-thermal radiation. According to the physics properties of tank steel Q235B, the time to failure (ttf) of the tank was analysed. The results show that the temperature rise rate affected by the coupling effect of multi-thermal radiation is significantly higher than that affected by single heat radiation; when the storage tank is affected by the single heat radiation, the time to failure is about 22min; when the storage tank is affected by the coupling effect of multi-thermal radiation, the time to failure is about 15min.
