A pressure vessel burst (PVB) is an explosion scenario commonly encountered at chemical processing and petroleum refining facilities. Existing methodologies are available to predict the blast loads resulting from a spherical or cylindrical PVB source, with the PVB source either at grade or at an elevation. In the case of an elevated PVB source, the resulting blast wave will reflect from the ground at an angle. This ground level reflection will result in the formation of a Mach stem at certain angles between the incident blast wave and ground, with the required angles dependent on the blast wave overpressure. The triple point associated with the Mach stem moves upwards as the Mach stem progresses forwards, which can create a region of high blast pressure. This paper focuses on the investigation of a methodology that can be used to determine the high-pressure region generated by the Mach stem, along with the associated blast pressure, as a function of the PVB source elevation and incident blast pressure.
Mr. Lowry is a member of BakerRisk’s Blast Effects Group. His work is focused on experimental combustion research and CFD (Computational Fluid Dynamics) modeling of explosion phenomena. Mr. Lowry has 15 years of experience in experimental research of hydrocarbon combustion, particularly LBV (Laminar Burning Velocity) measurements of fuel-air-inert systems. Analytical efforts focus on explosion protection using simplified and CFD approaches, as well as modeling flammability and explosion phenomena in support of commercial projects and litigation.
Dr. Geng is a member of BakerRisk’s Blast Effects Group. His work focuses on research and development of 3-D CFD (computational fluid dynamics) code and visualization systems capable of simulating generation and propagation of blast and shock waves and their interaction with structures or buildings. Dr. Geng has successfully developed a robust three-dimensional computational fluid dynamics code, BWTI© (Blast Wave-Target Interaction), which is routinely used in project work for BakerRisk.
As the biofuels industry continues to expand in support of global decarbonization mandates and objectives, facility owners and developers are being challenged to balance production efficiency, operational reliability, and personnel safety.
As high hazard facilities, biofuels sites should focus on developing a fire protections strategy informed by performance-based analysis so strategies implemented meet the unique challenges found at each facility.
