The Effect of Jacket-Side Liquid on the Burst Pressure Estimation of a Jacketed Vessel

This study is intended to clarify the influence of jacket-side liquid on determining the burst pressure of a jacketed vessel subjected to deflagrations inside the vessel chamber. The influence of jacket-side liquid is modeled as either being nearly incompressible due to its high bulk modulus or sustaining a constant level of jacket chamber pressure. Employing finite element analyses, this paper reveals how jacket-side liquid compressibility affects the interaction between the vessel shell (inner wall) and jacket (outer wall) when the vessel shell is subjected to an internal deflagration. The study results indicate that simply combing the separate burst pressures of the vessel shell and jacket can result in insignificant difference in calculating the burst pressure of the jacketed vessel that is made of ductile materials and has a relatively small gap between the vessel shell and jacket.
