Abstract EN
Blast waves generated by cylindrical TNT explosives in partially confined chamber were studied numerically and experimentally.
Based on the classical fifth-order weighted essentially nonoscillatory finite difference schemes (fifth-order WENO schemes), the 1D, 2D, and 3D codes for predicting the evolution of shock waves were developed.
A variety of benchmark-test problems, including shock tube problem, interacting blast wave, shock entropy wave interaction, and double Mach reflection, were studied.
Experimental tests of explosion events in a partially confined chamber were conducted.
Then, the 3D code was employed to predict the overpressure-time histories of certain points of chamber walls.
Through comparing, a good agreement between numerical prediction and experimental results was achieved.
The studies in this paper provide a reliable means to predict the blast load in confined space.
