Objective of this study is to analysis the MHD flow over a curved stretching surface. In this model we incorporated the radiation, mixed convection and partial slip parameter. Using a curvilinear coordinate system developed a mathematical model and the system of basic governing equations are converted into ordinary differential equations with appropriate transformations. The obtained results are solved by using bvp4c solver. The numerical; results for the velocity and temperature as well as the physical quantities such as skin friction and rate of heat transfer are determined and discussed through graph. Results shown that the velocity and temperature decreases with increasing values of curvature parameter and but for magnetic parameter velocity decreases whereas temperature profile increase. Comparison with previous literature are also shown in tabular form and found excellent agreement. Dhaka Univ. J. Sci. 69(3): 171-178, 2022 (June)

The impact of variable fluid properties (viscosity and thermal conductivity) and magnetic dipole on biomagnetic Maxwell fluid past a stretching sheet with slip velocity and heat generation/absorptionhave been studied. Similarity transformation technique is adopted to obtain the self-similar coupled nonlinear ordinary differential equations. Using similarity variable, the basic governing equations with boundary conditions are transformed and solved in bvp4c technique with MATLAB software. The contribution of different pertinent parameters such as viscosity, thermal conductivity and ferromagnetic parameter on the flow profiles with physical quantities are analyzed and examined through graphically. Results shown that with increasing ferromagnetic parameter, slip parameter, Maxwell parameter, velocity decreases but temperature increases. For accuracy of the proposed model to compare our numerical results in numerically and graphically with the previousliterature under some limiting cases and a good agreement is found. Dhaka Univ. J.
