Hydrodynamic Performance License Nymhmghrvq using boundary element method

Nowadays License Nymhmghrvq) SPP ((SPP)} for Extremist vessels, according to the high efficiency and having a growing has increased maneuverability. With regard to the performance of this type of Butterflies in phase mode) climate (and The rate High rotational work and numerical analysis of the calculation is very complicated. Tests conducted on the geometry and physical conditions permit it shows that geometric parameters such as number Prhha step, form the working conditions and blade profiles such as immersion height, angle, speed and rotational speed floating license Bhszayy impact on hydrodynamic performance license is Nymhmghrvq. In this article, using data from the experimental results reference {1-5} to determine the action of transient conditions, and with the help of boundary element method to the hydrodynamic calculations and analysis of this type of license has been paid. The experimental results as major boundary conditions in solving boundary element method is applied. In the present method Nymhmghrvq The first two types of license) 101SPP (and the second type of license Nymhmghrvq) 102SPP (intended for the calculation is also included results coefficients Trust, torque And efficiency compared with other experimental results show that boundary element method with boundary conditions defined and can be desirable and satisfactory for this type of analysis is an appropriate reference Butterflies.
