Abstract

In the present paper, we have investigated peristaltic flow of single wall carbon nanotubes (SWCNTs) in a curved channel with variable viscosity. The present problem is modeled and exact solutions for non-dimensional differential equation are achieved under long wavelength and low Reynolds number approximation. The features of the peristaltic motion are examined by plotting graphs and discussed in detail. Velocity tables are also incorporated for different values of volume fraction of the nano particle material and for viscosity parameter. Results showed that addition of SWCNTs decreases nano particle temperature and velocity profile near the left wall. It is found that for pure blood case, velocity for the variable viscosity fluid is greater as compared to the constant viscosity fluid. It is also found that for the case of SWCNTs, velocity for the variable viscosity fluid near the left wall decreases whereas it gets opposite behavior near the right wall.
