The extreme energy engineering studies energetic materials such as explosive and propellants as well as lasers in high pressure and temperature conditions. Properties of the materials under these extreme conditions are significantly different from those observed under normal atmospheric environment. The processes which a propellant undergoes in a rocket are analyzed and physical phenomenon of explosive combustion process are simulated using our own hydro-code based on thermal-fluid dynamic principles. Experimental research on laser applications in the field of bio-medical, combustion, space exploration, and forensic science is also conducted. The research conducted produces promising results in various fields by establishing the basis of extreme energy principles.
