Sensitivity analysis is applied to ship manoeuvring mathematical models as a means of dealing with model uncertainties, and often leads simplifications. A rather standard 3DOF was tuned the available results full-scale trials naval combatant further used reference for sensitivity analysis.

Transition is the basic phenomena of complex flow regime changes in fluid mechanics. So far, axiomatic expression and rigorous mathematical description transition separation are important scientific problems, which also great significance to development Applied Science. This article obtaining conditions general for through excited state theory flowfield, derivation based on N-S equations, combi...
