Overpressure Functions of Blast Waves for Explosions in Air

LIN Da chao 1,BAI Chun hua 1,ZHANG Qi 1,2 (1.National Key Lab of Explosion and Safety Science, Beijing Institute of Technology,Beijing 100081,China; 2.Xi′an University of Science and Technology,Xi′an 710054,Shanxi,China)  
The regularity of blast wave overpressures for explosions in air was studied analytically.On the bases of an introduced overpressure transmission function with vector form and the continuum condition of overpressure propagation,a governing equation was suggested.From the equation,a general overpressure function is presented.The function is concerned with the overpressure of one dimensional blast waves in positive phases.Several forms of overpressure functions given previously were also derived from the function.This fact shows the generality of the function suggested.
