Original Article


The purpose of this analysis is to highlight the CNTs characteristics in peristaltic flows through non-uniform channels. Viscosity is considered temperature in this analysis. Peristaltic walls comprise the momentum and thermal slip effects. Radiative heat flux is also taken into account to study the thermal radiation aspects. Physical properties for CNTS (i.e. single and multiple wall) are used which was suggested by Iijima. Flow equations are modeled in view of mass, momentum and energy conservation principles. Moreover, such equations are simplified through lubrication assumptions. Solution for flow quantities is carried out in the form of exact solution. Numerical integration technique is used for pressure rise per wavelength plotting. Bar charts are made for effective heat transfer rate analysis.
