Research Progress of Nuclear Explosion Photo Thermal Radiation
摘要
Abstract
The intense photo thermal radiation caused by nuclear explosions is one of the main ways of releasing energy from nuclear weapons,which has instantaneous nature and extremely high radiation intensity.Firstly,this paper reviews the research history of nuclear explosion fireballs and photo thermal radiation,including the solution of the radiation hydrodynamics equations,theoretical and experimental study on nuclear explosion fireballs,as well as simulation of optical radiation transport and thermal radiation.Secondly,the diverse methods adopted by researchers in studying photo thermal radiation over years are summarized,and various computational strategies,such as finite difference method,operator splitting method,explicit and implicit processing,are discussed.Thirdly,the related formulas and characteristic parameters related to the three stages and two iconic pulses of the development process of fireballs proposed by many researchers are summarized.Finally,the application of neural networks in the field of nuclear explosions are introduced.Based on current scientific understanding,a prospective analysis is conducted on the potential application and feasibility of neural networks in the future field of photo thermal radiation.关键词
