In this work, high-speed drop impact onto deep volume of the same liquid is numerically studied in 3D using Direct Numerical Simulation (DNS). The numerical results are compared with the previous experimental works by Murphy et al. [1]. Most of the distinctive features during the impact, including the evolution of the crown and cavity, the ligaments emanating from the rim of the crown, the formation of the bubble canopy, the central spiral jet that pierces through the bottom of the cavity and the subsequent broad upward jet, are correctly reproduced. The trajectory of the upper rim of the crown as well as the depth and width of the subsurface cavity are tracked during the simulation. Very reliable quantitative agreements between numerical and experimental data are obtained with respect to the time evolution of the crown rim and cavity dimensions. The simulation shows very good qualitative and quantitative agreement against the available experimental data, which enables the further investigation of the internal mechanisms of drop impact in the future
