The propagation law of shock wave overpressure in nuclear explosion fusion power plant

The shock wave will be created in the process of generating electricity in the nuclear explosion fusion power plant, whose propagation law of overpressure is an important foundation for the design of cavity wall. However, there is a certain lack of describing the peak overpressure of shock wave in the existing equations (for example, relative error is great). A new equation of the peak overpressure of shock wave, the time of positive pressure τ ₊ and the propagation coefficient of shock wave ω are suggested by theoretical analysis, from which we get the propagation law of shock wave. The comparative result indicates that the new equation is more suitable than the existing equations for solving the peak overpressure of shock wave in the power plant.
