A comparative study of γAl2O3−H2O and γAl2O3−C2H6O2 near boundary layer non-linear curved surface

Abstract This analysis addresses the impact of heat generation and MHD on nanofluid flow near a nonlinear curved surface. For an inclusive and representative analysis most common fluids like ethylene glycol and water are chosen as base fluids and alumina particles are treated as nanoparticles. The alumina particles are considered due to their high conductivity. The mathematical model of nanofluid flow under different assumptions are generated using curvilinear coordinates which gives set of ordinary differential equations. Computational analysis is performed by using “Bvp4c” on computational software MATLAB. It is found that the velocity profile increases by increasing the values of curvature parameter, power law index and volume fraction of nanoparticles for two cases without and with effective of P r numbers. Moreover, the base flow temperature decreases for effective P r number corresponding to both nanofluids while an opposite behaviour occurs for without effective Prandtl number. Furthermore, the graphs are drawn for velocity and temperature for two different cases (with and without effective Prandtl numbers).
