The authors find that the Florida Cur- rent transport and upper mid-ocean transport of the model are underestimated against the observations. The simulated variability of MOC and MHT show a high correlation with the observations, exceeding 0.6. Both the simulated and observed MOC and MHT show a significant seasonal variability. According to the power spectrum analysis, LICOM can represent the mesoscale eddy characteristic of the MOC similar to the observation. The model shows a high correlation of 0.58 for the internal upper mid-ocean transport (MO) and a density difference between the western and eastern boundaries, as noted in previous studies.展开更多

The performed investigation has shown that large-scale HE (High explosives) particles mix up and split down to smaller sizes in the result of shock wave impact, instability development on the HE-EP (Explosion product) interface and vortex flow; at these sizes, due to the developed surface of the HE-EP contact, HE has enough time to get heated (energy transfer from EP), and the decomposition reaction effectively continues. Numerical modeling make the calculation of the hot spot growth rate (about 100-200 m/s) possible. This has proved the hypothesis saying that at mechanical material transport the turbulence in the reaction zone plays an important role and it must be taken into account in the detonation theory.展开更多
