Experimental validation of Viper underwater explosion CFD solver

In the last few decades, the situation on the water edges of the NATO borders proved that there is a growing need for accurate modelling of underwater explosive events. Traditionally, predicting loading conditions for these events relied on CPU-based solving tools, which, while effective, often required significant computational resources and time. Viper::Blast has now been extended to include a novel underwater explosive CFD prediction tool, leveraging advanced GPU technologies to enhance performance and reduce computation times. This paper evaluates the capability of the Viper::Blast underwater explosive CFD prediction tool by comparing its results with well-controlled experimental data. The comparison focuses on key metrics such as pressure, impulse, and wave propagation in underwater environments. By assessing the accuracy and efficiency of Viper::Blast in these scenarios, the paper demonstrates its potential as a reliable and fast alternative to traditional CPUbased methods for underwater blast modelling.
