Abstract: A high-resolution computational framework is established to solve the shaped charge jet. An expression which can be used in the Eulerian code, considering temperature rises caused by both shock waves and plastic work, is proposed. The selfdeveloped code is validated by a benchmark test, which is the detonation of a TNT slab. The numerical simulations of shaped charge jets are carried out. The processes of the explosive detonation, the collapse of the liner and the formation of the jet are numerically simulated. The influences of the liner configurations on the jet shape, velocity and temperature are analyzed. It is found that the jet is shorter and has lower velocity with a larger apex angle, but more liner material becomes jet. During the initial stage of the explosive loading, the smaller the apex angle, the higher the liner temperature. After the jets are formed, the temperatures of the jets with different liner shapes are close to each other.
