Highlights: [•] The aim of this work is to correlate the production of OH radicals to the temperature and pressure achieved in the bubble during the strong collapse. [•] The employed model combines the dynamic of bubble collapse in acoustical field with the chemical kinetics of single bubble. [•] The computer simulations showed the existence of an optimum bubble temperature of about 5200±200K and pressure of about 250±20MPa. [•] The results of the numerical simulations revealed that the main oxidant created in an O2 bubble is OH radical. [ABSTRACT FROM AUTHOR]
