“…The non-linearity of the resulting system suggests the application of the perturbation method about the small wave number δ. Thus we get the series form of solutions to plot graphs corresponding to the stream function, temperature, concentration and heat transfer coefficient (Z) as follows (Hayat, Rafiq, et al, 2015):…”

“…In particular, Turkyilmazoglu and Pop (2013) reported heat transfer effects with Jeffery fluid, while Jalil, Asghar, and Imran (2013) found the heat transfer mechanism on the moving surface of a free stream. Hayat, Rafiq, Ahmad, and Yasmin (2015) looked at the impact of melting heat transfer on peristalsis with thermal radiation and Joule heating, and Tripathi (2013) presented a transient heat flow analysis. Further, Ali, Sajid, Javed, and Abbas (2010) examined the heat transfer phenomenon in curved channel, while Sheikholeslami, Hatami, and Ganji (2014) carried out an analysis on nanofluid heat transfer with a magnetic field.…”

This paper addresses the influence of newly-developed Cattaneo-Christov heat flux model on peristalsis. Analysis has been carried out in a two-dimensional planner channel with wall properties and the Soret effect. An incompressible viscous fluid fills the space inside the channel. The relevant mathematical modeling is developed and a perturbation technique is employed to obtain a series form of solutions about small wave numbers. Expressions of velocity, temperature, concentration and heat transfer are treated graphically, corresponding to elasticity parameters, relaxation time and Prandtl numbers specifically. The graphical results are found distinctive that offers challenging role for further research on the topic. Further, the results of Fourier's law can be verified when the relaxation time of the Cattaneo-Christov heat flux model is considered absent or concepts of large wavelength and small Reynolds numbers are applied.

“…The upper urinary tract consists of the kidney and ureter. The main function of the upper tract is to collect urine and propel urine to the bladder, where urine is stored temporarily and periodically to eliminate waste from the body [3,4]. The pacemaker plays a crucial role in the urinary system by generating the peristalsis wave in the ureter.…”

Ureters are essential components of the urinary system and play a crucial role in the transportation of urine from the kidneys to the bladder. In the current study, a three-dimensional ureter is modelled. A series of peristaltic waves are made to travel on the ureter wall to analyze and measure parameter effects such as pressure, velocity, gradient pressure, and wall shear at different time steps. The flow dynamics in the ureters are thoroughly analyzed using the commercially available ANSYS-CFX software. The maximum pressure is found in the triple wave at the ureteropelvic junction and maximum velocity is observed in the single and double wave motion due to the contraction produced by the peristalsis motion. The pressure gradient is maximum at the inlet of the ureter during the single bolus motion. The contraction produced a high jet of velocity due to neck formation and also helps in urine trapping in the form of a bolus, which leads to the formation of reverse flow. Due to the reduction in area, shear stress builds on the ureter wall. The high shear stress may rupture the junctions in the ureter.

“…They found that the rotational velocity and temperature distributions enhance with an increase in the Reynolds number. Hayat et al [14] employed the perturbation technique to analyze the melting heat transfer of peristaltic flows in the presence of viscous dissipation and Joule heating. They also analyzed the oscillatory heat transfer caused by the sinusoidal traveling wave in a channel.…”

In the present paper, we focus on the melting heat transfer characteristics of Casson fluid involving thermal radiation and viscous dissipation. To this end, the governing partial differential equations (PDEs) are transformed into the ordinary differential equations (ODEs) via the similarity variables. Besides establishing a homotopy-based methodology and its optimization performed in MATHEMATICA package BVPh2.0, the present findings are compared and validated by those available results in the literature. It can be shown that regardless of the variable fluid properties, this methodology predicts the heat transfer rate with and without melting effect at any Prandtl number. Furthermore, it is seen that the velocity distribution is significantly affected by the melting parameter.
