In nanoscale structure sizes, the surface-to-bulk energy ratio is high and the surface effects must be taken into account. Surface effect plays a key role in accurately predicting the vibration behavior of nanostructures. In this paper, the wave behaviors of a single-walled carbon nanotube (CNT) conveying fluid are studied. The nonlocal Timoshenko beam theory is used and the surface effect is t...
This paper describes thermal modeling of Vapor Compression Refrigeration System using R134a in primary circuit and AL2O3-Water based nanofluids in secondary circuit. The model uses information of the secondary fluids input conditions geometric characteristics of the system, size of nanoparticles and the compressor speed to predict the secondary fluids output temperatures, the operating pressure...
Active Control of Cantilevered Pipes Conveying Fluid. Stabilization with Constraint on Input Energy.
The effect of non-stationary external forces on the vibration pipelines made composite materials is investigated in paper. A mathematical model pipeline developed, considering viscosity properties structure and base material, axial forces, internal pressure, resistance disturbances. viscoelastic conveying fluid under vibrations constructed based Boltzmann-Volterra integral model. to study a Eul...
Construction of nano-devices that can generate controllable unidirectional rotation is an important part of nanotechnology. Here, we design a nano-turbine composed of carbon nanotube and graphene nanoblades, which can be driven by fluid flow. Rotation motion of nano-turbine is quantitatively studied by molecular dynamics simulations on this model system. A robust linear relationship is achieved...
