چکیده مقاله
In this work, nonlocal vibration of double of
carbon nanotubes (CNTs) system conveying
fluid coupled by visco-Pasterna
k medium is carried out based
on nonlocal elasticity theory
where CNTs are placed in uniform temperature change and magnetic field. Considering
Euler-Bernoulli beam (EBB) model and Knuds
en number, the governing equations of
motion are discretized and Ritz method is appl
ied to obtain the frequency of coupled CNTs
system. The detailed parametric study is condu
cted, focusing on the remarkable effects of
the Knudsen number, aspect ra
tio, small scale, thermo-ma
gnetic fields, velocity of
conveying fluid and visco-Paster
nak medium on the stability of coupled system. The results
indicate that magnetic field has significant ef
fect on stability of coupled system. Also, it is
found that trend of figures ha
ve good agreement with the prev
ious researches. Results of
this investigation could be applied for optimum design of nano/micro mechanical devices
for controlling stability of coupled systems
conveying fluid under thermo-magnetic fields.
