Effects of Non-Integral Number of Peristaltic Waves Transporting Couple Stress Fluids in Finite Length Channels
نویسندگان
چکیده
Peristaltic flow of couple stress fluids is studied here in a finite length channel. The analysis is carried out under the assumption of long wavelength and low Reynolds number approximations. When the couple stress parameter increases, it is found that pressure diminishes, maximum averaged flow rate increases, mechanical efficiency decreases, area experiencing reflux reduces, and trapped bolus-size increases. A comparative study of integral and non-integral number of waves propagating along the channel is also done.

متن کاملUnsteady Peristaltic Flow of Micro-Polar Fluid in a Finite Channel
This is an attempt to model an unsteady peristaltic flow of micro-polar fluid in a channel of finite length. The channel is subjected to progressive sinusoidal waves that help the walls contract and relax but not expand beyond the natural boundary. It is found that the coupling number increases pressure along the entire length of the channel, while the micro-polar parameter decreases it. The co...
