The peristaltic transport of liquid has gained exceptional interest in the recent time owing to its extensive application in physiology as it is considered a vital method for flow in bio fluids. This course is exceedingly essential in numerous physiological systems and in engineering includes swallowing food through esophagus, arterioles and capillaries, in sanitary fluid transportation, toxic fluid move in the nuclear engineering etc. Several investigators have analyzed the peristaltic motion of both Newtonian and non-Newtonian fluids in mechanical as well as physiological systems

To acquire improved quantitative and qualitative characteristics concerning the rheological activities of blood, several authors presented numerous non Newtonian fluid models. Jeffrey fluid amongst them is a well-known model in studying vascular dynamics. The magnetic field effect in two-dimensional mixed convection boundary layer flow and heat transfer of a Jeffreyfluid over a stretched sheet immersed in a porous medium is studied by Kartini Ahmad, Anuar Ishak

The published studies about the heat generation in peristaltic MHD flows of non-Newtonian fluids are still scarce. In fact heat generation and absorption concepts in fluids have relevance in problems dealing with chemical reactions, geo-nuclear repositions and these concerned with dissociating fluids. The nanofluid flow with thermal and chemical reaction has broad applications in cooling, expulsion procedures and polymer industry. The magnetic field plays an essential role in targeting drugs by magnetic nano particles for different kinds of diseases in a human body. The Jeffrey fluid model is employed to simulate non-Newtonian characteristics. Hence the current model is to describe heat generation and chemical reaction peristaltic pumping of MHD Jeffrey nanofluid. Thermal radiation in addition to chemical reaction effects has been addressed.

The impact of nanofluid particles on the peristaltic bloodstream has been explored scientifically under the effects of thermal radiation and chemical response with the guide of the computational program Mathematica. The base liquid is considered as a Jeffrey fluid model within sight of an applied magnetic field. The administering flow is displayed for low Reynolds number and long wavelength.The present paper focused on heat generation and chemical reaction in flow propagated by peristalsis in hydro magnetic Jeffrey fluid with thermal radiation taking into consideration. The main findings are listed below.

Velocity increases with the larger values of M at the channel walls. Velocity is enhanced in the lower part of the channel with increasing Gr, Nt and λ, whereas it behaves in converse with the chemical reaction parameter.

It is observed that temperature (θ) decreases with Rn, λ. It is found that θ increases with increase in γ, β.

Increase in γ increase in concentration profile (ϕ). Similar behavior is found with the case radiation parameter (Rn). A converse behavior can be found with the case of thermophoresis (Nt), heat source parameter (β).
