“…The majority of these are government codes and not available to the general public but can be used on government projects if approval is granted. CEBAM was developed specifically for use by the safety and security community for hazard assessments [1][2]. Here its capabilities in addressing high-explosive events are briefly reviewed.…”

“…Figure 2 shows how the incident blast wave produced by a charge reflects off the buildings bordering a street and causing the load on the structures to be not a single pulse as assumed by the simple methods but a collection of pulses. This scenario has been used by code such as Air3D to benchmark their accuracy [5]. Therefore that data is shown along with results from CEBAM.…”

Computational modeling is routinely used in the design and development of explosive systems but is not typically applied in performing hazard assessments related to explosives. Typically simplified models are used to perform analysis related to safety and security applications involving explosives. These models can misrepresent the destructive output from explosive devices because they do not resolve many of the aspects of the scenarios such as wave reflection, channeling and focusing of blast waves. Here a computational model developed specifically for explosive hazard assessments is reviewed and the advantages as compared to simple models are highlighted. Some of the obstacle to applying computational modeling to routine explosive hazard assessment problems is the ability to perform analysis in a timely manner and address the wide range of explosives encountered. Here techniques being developed to increase flexibility in application and increase efficiency are presented.

“…The energy component, o E , is analogous to the heat of formation of the material and since the convention commonly used with the JWL is to define this quantity as a positive number, the value must be subtracted from Equation (13) to produce the correct energy release effect. The pressure of the mixture can be calculated using ( )…”

AAC/PA Approval and Clearance # 11-06-07-630, dated 6 November, 2007 SUPPLEMENTARY NOTES ABSTRACTThe mechanical and chemical processes that occur in the explosives found in munitions systems are important to the entire life cycle of the system. Examples of these processes are found in the accidental detonation of weapons while in storage or transport, the premature initiation of a warhead during employment, and the destructive output from the system when functioned as designed. The complete range of possible processes encompasses a wide variety of chemical and mechanical phenomena and depending on the scenario, the dominant phenomenon changes. An essential tool for the design and analysis of these systems is a computational model that can predict a range of scenarios. It is such a tool that is the focus of this proposed effort.

“…However, the issue of explosion/construction interaction is only briefly described. Clutter et al [4] show some CFD results on an explosion propagation that is simulated in some modelled urban area. The model is based on the compressible Euler equations, and therefore their paper is quite similar to this research paper (see next section).…”
