“…There have been 4 numerous numerical studies of peristaltic transport [14,'15, 16], where the restrictions on various parameters are less prohibitive than in theoretical studies. Recently there have been numerical studies of closed cavity peristalsis [17,18] and solid particle suspensions [19,20,21], as well as innovative theoretical studies [22]. To the best of the authors' knowledge, the work of Fauci [23], utilizing the Immersed Boundary Method (IBM), was the only previous numerical instance of peristaltic transport of a finite-sized particle.…”

Peristaltic transport refers to a class of internal fluid flows where the periodic deformation of flexible containing walls elicits a non-negligible fluid motion. It is a mechanism used to transport fluid and immersed solid particles in a tube or chan nel when it is ineffective or impossible to impose a favorable pressure gradient or desirous to avoid contact between the transported mixture and mechanical mov ing parts. Peristaltic transport occurs in many physiological situations and has myriad industrial applications. We focus our study on the peristaltic transport of a macroscopic particle in a two dimensional channel using the Lattice Boltzmann Method(LBM). We systematically investigate the effect of variation of the relevant dimensionless paJ'ameters of the system on the paJ·ticle transport. We find , among other results, a case where an increase of Reynolds number CaJl actually lead to a slight increase in particle transport, and a case where as the wall deformation•Author to whom correspondence should be addressed. Electronic mail: kconninl @jhu.edu 1 1 increases, the motion of the particle becomes non-negative only. VVe examine the particle behavior when the system exhibits the peculiar phenomenon of fluid tmp ping. Under these circumstances, the particle may itself become tmpped where it is subsequently transported at the wave speed, which is the ma.ximum possible transport in the absence of a favorable pressure gradient . Finally, we analyze how the particle presence affects stress, pressure, and dissipation in the fluid in hopes of determining preferred working conditions for peristaltic transport of shear-sensitive particles. We fiud that the levels of shear stress are most hazardous near the throat of the channel. We advise that shear-sensitive particles should be transported un der conditions where tmpping occurs as the particle is typically situated in a region of innocuous shear stress levels.

The flow through asymmetric nonuniform (convergent) channels with the effect of the magnetic field have a pronounced impact in engineering and biological fields such as chemical and food industries, blood flow through capillaries, and arteries, and so forth. With this motivation, the present study focuses on convective hydromagnetic particulate suspension flow in an asymmetric convergent channel under the heat generation effect. The numerical method is applied to solve the nondimensionalized equations governing the transport process of fluid and particle flow and its heat. To check the convergence of the computational results, a grid independence test has been performed. A comparison test has been made to validate the results and an admirable agreement is noticed with published results. Computation results are reported for the influence of emerging parameters on the fluid as well as particle velocity and temperature profiles through graphs and tables. A method of slope linear regression through data points is presented to study the impact of various parameters on skin friction and Nusselt number.

In this article an attempt has been made to dscuss the velocity and temperature slip effects on MHD convective two phase particulate suspension flow in a convergent channel with viscous dissipation .The non dimensionalised governing equations are solved using Runge-Kutta shooting method.The results obtained are represented graphically for various emerging parameters.The skin friction coefficient and Nusselt number are obtained and validated with existing results.It is found that with an increase in velocity slip parameter the velocity of the fluid increases.The fluid phase temperature decreases with an increase in temperature slip parameter.
