This unique book is a store of less well-known explosion and

detonation phenomena, including also data and experiences related to

safety risks. It highlights the shortcomings of the current

engineering codes based on a classical plane wave model of the

phenomenon, and why these tools must fail.

For the first time all the explosion phenomena are described in terms

of proper assemblages of hot spots, which emit pressure waves and

associated near field terms in flow. Not all of the approaches are

new. Some even date back to the 19th century or earlier.. What is new

is the application of these approaches to explosion phenomena. In

order to make these tools easily available to the current detonation

physicist, basic acoustics is therefore also addressed.

Whereas the current plane wave, homogeneous flow detonation physics

is an excellent engineering tool for numerical predictions under

given conditions, the multi-hot-spot-model is an additional tool for

analyzing phenomena that cannot be explained by classical

calculations. The real benefit comes from being able to understand,

without any artificial assumptions, the whole phenomenology of

detonations and explosions. By specifying pressure generating

mechanisms, one is able to see that the current treatment of the

detonics of energetic materials is only a very special – but powerful

– case of explosion events and hazards. It becomes clear that

physical explosions must be taken into account in any safety

considerations. In these terms it is easy to understand why even

liquid carbon dioxide and inert silo materials can explode.

A unique collection of unexpected events, which might surprise even

specialists, has resulted from the evaluation of the model. Therefore

this book is valuable for each explosion and safety scientist for the

understanding and forecasting of unwanted events. The text mainly

addresses the next generation of explosion and detonation scientists,

with the goal of promoting the science of detonation on a new

physical basis. For this reason gaps in current knowledge are also

addressed. The science of explosions is not fully mature, but is

still in its beginning – and the tools necessary for furthering the

understanding of these phenomena have been with us for centuries.
