Abstract:
In th is paper, a two-d imensional flow s of b last w aves in a w orkshop is sim ulated nume rica lly by using a h igh prec ise CE /SE m ethod. Interactional pr inc iples am ong blastw aves, obstacles and in ternal wa lls o f the wo rkshop are analysed. A pressure contours chart is obta ined that can c lea rly show the vo lution o f shock structure. Num er ica l results show com plex w ave systerm as b last w aves re flecting o r passing around the obstac les. By compar ing w ith the exp losive fie ld w ithout obstac les, w e ana lyze the influence wh ich obstac les w ith different d istance to cente r o f explosion po int effect on explosive fie ld. A t last, m ore analysis about the change of the exp los ive field have been m ade by chang ing the num ber o f exp losion po int. Num er ica l results acco rd w ith the re levant physical law s
