Hydro-mechanical analysis of pipe armed by nanoparticles based on numerical methods

Fluid influence on the hydro-mechanical response of pipes armed by nanoparticles is investigated here. Mori-Tanaka approach is utilised for calculating the structure equivalent properties assuming agglomeration influences. The famous Navier-Stokes relation is applied for deriving the fluid force. According to the Reddy theory of shell, the equations of motion are obtained utilising principal of Hamilton and method of energy. The critical velocity of fluid and frequency of system are presented using numerical approach and the influences of nanoparticles volume fractions and agglomeration as well as pipe geometrical variables are assumed. Results present that enhancing the nanoparticles volume fractions, the critical velocity of fluid and frequency of the structure are enhanced.
