Energy released in an explosion

Click For Summary
SUMMARY

The discussion centers on the energy released during a bomb explosion and the relationship between this energy and the expansion of the blast wave radius. Participants seek a formula to describe the shock wave resulting from TNT explosions. Resources such as the website "makeitlouder.com" provide technical insights into bomb shock wave estimation. The thread was ultimately closed due to the forum's policy against discussing dangerous activities.

PREREQUISITES
  • Understanding of basic physics concepts related to energy and shock waves
  • Familiarity with TNT and its explosive properties
  • Knowledge of mathematical formulas related to wave propagation
  • Basic research skills for sourcing technical information online
NEXT STEPS
  • Research the "TNT equivalent" and its application in calculating explosion energy
  • Study the "Navier-Stokes equations" for fluid dynamics related to shock waves
  • Explore "blast wave modeling" techniques used in physics
  • Investigate online resources for "explosion dynamics" and related simulations
USEFUL FOR

Students in physics, engineers specializing in explosive materials, and researchers interested in the dynamics of shock waves from explosions.

Hi All, I'm working on a problem about describing the energy released when a bomb explodes, assuming it releases energy, E, I'm trying to describe the rate at which the radius of the bomb blast wave is expanding. I'm having some difficulty conceiving where to start in connecting the energy released to the radius of the explosion. Thanks in advance for all the help :)

I am actually having the same problem.. Could someone please be kind enough to explain a formula which describes a shock wave coming from an explosion of, let's say, TNT?
 
This information is readily available on the Internet. I Googled TNT Shock Wave, and got lots of hits. Many were YouTube videos unfortunately, but some were more techincal in nature. This is one that may help you:

Since discussions of dangerous activities are not allowed on the PF, I'm going to close this thread. You can find more hits by doing the Google search yourself.
