Abstract
- The purpose of present analysis is to explore the peristaltic flow of Williamson nanofluid in an endoscope. Inner tube is rigid while the outer is subject to sinusoidal peristaltic wave. The outer tube satisfied partial slip condition while inner tube has no slip condition. Complaint wall properties are considered. Such preferences are practical in blood capillaries where inner radius of tube is very small. Long wave length and small Reynolds number are taken into account. Numerical study is performed for the outcoming problem. Impact of physical quantities are discussed through graphs for velocity, temperature and concentration respectively. The attributes of this study are presented in last section and a good agreement is found with existing literature. It is concluded that slip causes decrease in velocity and temperature. Whereas temperature and concentration give opposite response wih rise in thermophoresis and Brownian diffusion.
