ABSTRACT The effect of chemical reaction on MHD free convection heat transfer flow of a nanofluid bounded a semi-infinite flat surface in a rotating frame of reference is theoretically investigated. The velocity along the plate (slip velocity) is assumed to oscillate on time with constant frequency. The analytical solutions of different water based nanofluids containing TiO2, Al2O3, Ag, Cu and CuO of the boundary layers are assumed, to keep the problem as realistic as possible. The dimensionless governing equations for this investigation are solved analytically by using the small perturbation Technique. The effects of various physical parameters on velocity, temperature and concentration fields are presented graphically. The enhancement in magnetic parameter leads to a considerable reduction in velocity and chemical reaction parameter is predominant in controlling the concentration profile. The results obtained in the simulation of perturbation method are in well agreement with realistic situation of the scientific scenario. Keywords: Chemical reaction, water based nano-fluids, Rotating frame, constant heat source. * Corresponding Author: dharma.g2007@gmail.com 1. INTRODUCTION The idea of nanofluid isn't new as in 1857 Michael Faraday initially announced the examination on the combination and shades of colloidal gold. The blend of suspended nanoparticles in a base fluid is typically alluded to as a nanofluid. Nature is brimming with nanofluids, similar to blood, a complex organic nanofluid where distinctive nanoparticles (at atomic dimension) achieve diverse capacities, and utilitarian parts effectively react to their neighborhood condition. As indicated by the sorts of fluids (natural and inorganic) and sorts of nanoparticles, one can get distinctive kinds of nanofluids like process extraction nanofluids, ecological (contamination controlling nanofluids), bio-, and pharmaceutical nanofluids. Another class of polymer nanofluids, drag- diminishing nanofluids, go for improved heat exchange, and in addition, stream grinding decrease. An extensive variety of dynamic self-get together systems for nanoscale structures begin from a suspension of nanoparticles in liquid. Present day nanotechnology enables one to process and deliver materials with normal crystallite estimate <50 nm. Nanofluid have someone of a kind highlights that are very not quite the same as regular two-stage stream blends in which μm as well as mm particles are suspended. Contrasted with a regular fluid and traditional two-stage blend, the nanofluid has higher thermal conductivity, does not square stream channels, and initiates a little weight drop. Strong particles are included as they lead warm much superior to a fluid. Furthermore, nanoparticles oppose sedimentation, when contrasted with bigger particles, because of Brownian movement and interparticle powers and have a lot higher surface zone (1,000-time) which improves the heat conduction of nanofluids since heat exchange happens on the surface of the liquid. Three properties that make nanofluids promising coolants are: (i) expanded heat conductivity,(ii) expanded single-stage heat exchange, and (iii) expanded basic heat motion. Research has demonstrated that generally little measures of nanoparticles, of the request of 5 Vol. percent or less, can upgrade thermal conductivity of the base liquid to a huge degree. Along these lines, abusing the extraordinary qualities of nanoparticles, nanofluids are made with two highlights essential for heat exchange systems:(i) outrageous strength, and (ii) ultra-high thermal conductivity. The ongoing research ever since then has extended to utilization of nano- fluids in microelectronics, fuel cells, pharmaceutical processes , hybrid- powered engines, engine cooling, vehicle thermal management, domestic refrigerator, chillers, heat exchanger, nuclear reactor coolant, grinding, machining, space technology, defense and ships, and boiler flue gas temperature reduction. A rotating frame of reference is used to model flows in rotating machines. In these cases, the flow is unsteady in an inertial frame (non- accelerating coordinate system in the inertial frame) because the blades or rotors sweep the domain periodically. However, it is possible to perform the calculations in a domain that moves with the rotating coordinate which is fixed on the rotating part. In this approach, the flow is steady relative to the rotating (non-inertial) frame, which reduces the expensive computations needed for an accurate analysis. This approach is appropriate when the flow at the boundary between the rotating parts and the stationary parts is weakly affected by the interaction. It provides a reasonable time-averaged simulation result for many applications. Rotating frames don't physically rotate anything and therefore do not show transient effects due to the real motion. Instead, a quasi-steady state solution is calculated due to the rotating equipment. Any problems where transient effects due to rotor-stator interaction are small are candidates to use the rotating frame of reference approach. A typical example is the mixing tank where the impeller-baffle interactions are Frontiers in Heat and Mass Transfer Available at www.ThermalFluidsCentral.org
