Description:

 

Scope: The course will cover basic concepts on shock and 

detonation physics for gaseous, homogeneous and 

heterogeneous explosives and will introduce the participants 

on modelling, hydrocode simulation and experimental 

techniques. The course will be given in two parts. 

Participants may register for either or both parts 

(discounts apply). The first part will focus on the physics, 

experiments and reduced modelling, while the second part 

will be devoted on the CFD simulation, including 

formulations and numerical methods for gaseous and 

condensed-phase combustion. 

 

Topics to be covered include: The course will cover a broad 

range of areas, including: 

 

Part 1: 

 

    * Introduction to Shock Physics; 

    * Explosion and Detonation Physics I; 

    * Detonation Physics II (Thermodynamic EoS, Rate forms, 

ZND and Wood Kirkwood); 

    * Detonation and Explosion Modelling (thermodynamic 

analysis, gas, condensed phase); 

    * Hot-Spot Ignition of Explosives; 

    * Non-ideal detonation modeling - quasi-1D (Role of hot 

spots - ex void collapse, adiabatic shear, Non-ideal 

detonation - shock front curvature, finite reaction zone, 

critical diameter, partial reaction and reduced VOD, Role of 

confinement, DSD, Program burn); 

    * Industrial and defense applications; 

    * Examples from CFD modelling; 

    * Experimental techniques for studies of explosives; 

    * Recent Research on Explosives including DDT Studies; 

    * Non-ideal detonation detonation modeling application 

quasi 1D; 

    * CFD applications.  

 

Part 2: 

 

    * Formulations for gaseous and condensed-phases 

(including augmented Euler, Baer-Nunziato and reduced B-N). 

    * Representation of chemistry (including Arhenius, 

reduced and full chemistry, pressure-based and ignition, and 

growth models). 

    * Numerical schemes. 

    * Mesh generation and mesh adaptation (AMR). 

 

The lecturers in Part 2 will demonstrate the theory and 

numerical methods via a number of case studies, including: 

 

    * Gaseous-phase shock-induced detonation. 

    * Shock-flame interaction and deflagration-to-detonation. 

    * Condensed-phase shock-induced detonation (rate stick). 

    * Condensed-phase propagation of detonation in curved ducts. 

    * Condensed-phase detonation using B-N and reduced B-N 

models. 

 

Working Plan: The lectures on the theory will be 

complemented by hands-on computational practicals during the 

afternoons. The participants may bring their own laptops to 

do the practicals and to connect to the server. Instructions 

on essential software and how to acquire it will be given at 

registration. We are able to provide a number of laptops for 

the duration of the course. There will be additional 

seminars which will demonstrate the application of the short 

course topic in industrial and academic practice. 

 

Who should attend: The course is suitable for researchers 

and practitioners from industry, research institutions and 

consultancy organizations. The course will also serve as a 

good introduction for those in managerial and policy-making 

positions. 

 

Attainable skills: At the end of the course the participants 

will have a firm understanding of detonation physics 

fundamentals, knowledge of the hierarchy of models employed 

for detonation modelling and siulations and hands-on 

experience using operational codes.
