Summary on Grant Application Form |
|
Air3d is an easy to use, fairly fast pc-based program that has been well-suited to the studies conducted under EPSRC award GR/M72425 'The influence of urban geometry on blast wave resultants and associated building damage'. This new proposal is to develop the program to make it capable of addressing more complex situations than is currently practicable. This will be accomplished by: (i) introducing static mesh refinement to allow larger physical domains to be addressed; (ii) studying realistic three-dimensional buildings/obstacles by means of 'cut' cells within the basic Cartesian grid structure; (iii) extending the program's ability to deal with explosives other than TNT (to handle two-component air/explosive products gases) particularly in situations where detonation occurs inside a building and (iv) introducing and implementing adaptive mesh refinement to improve greatly the program's ability to model blast wave fronts and contact discontinuities. Code development work will be complemented by validation against data obtained from experimental investigations of complex geometry scenarios at reduced scale, existing data from full-sized explosive trials and information extracted from studies of real-life explosive events such as accidental explosions and terrorist attacks. It is expected that Air3d will provide a sophisticated, yet still easy to use tool, that will allow a much wider range of compex geometry blast-structure interactions to be investigated with confidence.
