On Demand print-head (SOD) is performed. This work leads us to study (i) fluid structure/interaction with a vibrating tube conveying fluid, assimilated to a cantilever beam excited by a pointwise piezoactuator (PZA) (ii) fluid film instability with spray generation. After establishing a more general equation of the motion of a vibrating tube filled with fluid using Hamilton's modified principle...

Pneumatic conveying is widely used for transporting granular materials and agricultural products. Traditional flow visualization methods are used extensively in experimental fluid dynamics but have not been commonly used with agricultural products as the flow seeding particle. A flow visualization method that can provide qualitative flow visualization images and quantitative values to describe ...

In this paper, the nonlinear dynamic buckling of double-walled boron-nitride nanotube (DWBNNT) conveying viscous fluid is investigated based on Eringen's theory. BNNT is modeled as an Euler-Bernoulli beam and is subjected to combine mechanical, electrical and thermal loading. The effect of viscosity on fluid-BNNT interaction is considered based on Navier-Stokes relation. The van der Waals (vdW)...

In this paper, nonlinear dynamic behaviour of the carbon nanotube conveying fluid in slip boundary conditions is studied using the variation iteration method. The developed solutions are used to investigate the effects of various parameters on the nonlinear vibration of the nanotube. The results indicate that an increase in the slip parameter leads to a decrease in the frequency of vibration an...
