Este trabajo explora las caracter\u00edsticas de carga de las ondas de choque de detonaciones explosivas en entornos de aguas profundas utilizando un algoritmo multif\u00e1sico compresible de alto orden. El algoritmo utiliza m\u00e9todos num\u00e9ricos avanzados para t\u00e9rminos espaciales y temporales, con un m\u00e9todo de conjunto de niveles que captura interfaces multif\u00e1sicas y un modelo de combusti\u00f3n programada que simula las ondas de detonaci\u00f3n. La investigaci\u00f3n incluye validaciones num\u00e9ricas y experimentales de las ondas de choque en escenarios de aguas profundas y poco profundas, alineando los resultados con los datos te\u00f3ricos y experimentales. El estudio revela que los historiales de presi\u00f3n m\u00e1xima y presi\u00f3n-tiempo en explosiones en aguas profundas se desv\u00edan de los modelos existentes. Concluye que las f\u00f3rmulas actuales para calcular las duraciones de las ondas de choque son inexactas para las condiciones de aguas profundas, lo que ofrece nuevos conocimientos para futuras investigaciones.<\/p>\n
This study investigates shock wave load characteristics from condensed phase explosive detonations in deep-water environments using a high-order compressible multiphase solver. Spatial terms of the solver are discretized by fifth-order weighted essentially non-oscillatory reconstruction in characteristic space, while a third-order total variation diminishing Runge\u2013Kutta method is adopted to deal with the temporal terms. The level-set method captures multiphase interfaces, while a programed burn model describes detonation wave generation. Numerical and experimental validations focus on shock waves in explosives interacting with water. Validations across shallow and deep-water conditions align numerical results with theoretical and experimental values. The solver examines shock wave characteristics across varied charge masses and water depths, revealing peak pressure deviations under identical conditions. The numerical simulation results indicate that the similarity of shock wave loads in underwater explosions is evident not only in peak pressures but also in the pressure\u2013time history curves. Through extensive comparative analysis of results, it has been found that existing formulas for calculating shock wave positive pressure durations are not applicable to deep-water explosions. The research findings and analytical methods presented in this paper can serve as crucial references for further studies on the characteristics of shock wave loads in deep-water explosions.<\/p>\n
