In order to elucidate theoretically a reaction suppression mechanism of the nanofluids which made by dispersing metal nanoparticles in liquid sodium, experiment-integrated multiscale multiphysics computational chemistry simulators were developed and applied to the nanofluids. The pool oxidation burning simulator reprodueced well a self ending phenomenon of the nanofluids and the falling droplet burning simulator represented suppression of the temperature rise for the nanofluids, based on the cohesion energy of the nanofluids calculated by an artificial intelligence-integrated ultra-accelerated quantum chemical molecular dynamics method.
