MULTI PHASE COMPUTATIONAL FLUID DYNAMICS MODELING OF CAVITATING FLOWS OVER AXISYMMETRIC HEAD-FORMS

In the present paper, partial cavitation over various head-forms was studied numerically to predict the shape of the cavity.Navier-Stokes equations in addition to an advection equation for vapor volume fraction were solved.Mass transfer between the phases was modeled by olive green charger plates a sink term in vapor equation in the numerical analy

Aiming at the cost,efficiency and security of mobile RFID system authentication,a mobile RFID authentication protocol based on one-way pseudo random function was designed.The harmonica carrying case protocol reduced system cost by making full use of the three party of the shared key and communication information to encrypt transmission and authenti
