摘要：

Flow and heat transfer analysis of an electrically conducting MHD power law nano fluid is carried out through annular sector duct, under the influence of constant pressure gradient. Two types of nano particles (i.e. Cu and TiO2) are used in power law nano fluid. Strongly implicit procedure, (SIP) is used to simulate the discretized coupled algebraic equations. It has been observed that volume fraction of nano particles, phi and magnetic field parameter, Ha are favourable for the heat transfer rate, however, both resist the fluid flow. Impact of applied uniform transverse magnetic field exceeds in the case of shear thickening fluids (i.e. n>1) by increasing the value of Ha as compared to that in shear thinning fluids (i.e. n<1). Therefore, enhancement in heat transfer rate is comparably more in shear thickening fluid. Furthermore, comparable limiting case study with published result is also carried out in this research paper.
