Objective: The purpose of this article is to analyze the effects of different shaped Agnanoparticles
on peristaltic flow through curved tube with permeable walls.
Method: In the considered endoscope the inner tube is rigid while outer tube experience a sinusoidal
wave and both tubes make an annulus. Bricks, cylinders and platelets are different shaped Agnanoparticles.
Toroidal coordinate system is used to examine the nature of Ag-nanoparticles mathematically
in the curved tube with viscous fluid. Analysis is performed with the consideration of
low Reynolds number and long wavelength approximation. Perturbation approximation is used to
solve the problem and achieve results for pressure gradient, pressure rise, axial velocity and stream
Results: The effects of various parameters such as Grashoff's number, Darcy's number, radius of
the endoscope and amplitude ratio on flow variables have been discussed graphically. The contemporary
investigation has revealed that the temperature profile shows a decrease for larger shape factor
of Ag-nanoparticles. Pressure gradient exhibits higher results with larger Darcy's number. Also
trapped bolus tend to have bigger size for greater shape factor.
Conclusion: Temperature profile for the nanofluid decreases with the increase in shape factor m of
nanoparticles. The trapping phenomena reveal that the size of inner bolus appears larger for platelet
nanoparticles as compared to brick and cylinder nanoparticles.
