Abstract: Present contribution is the theoretical application of the thermal extrusion system associated with the various manufacturing processes. The problem is composed by utilizing the electrical MHD and radiation aspects on flow of Carreau nanofluid. Keeping industrial and mechanical applications in mind, the thermophoretic force and Brownian movement are also accounted. Here, flow is induced from periodically oscillation of the moving surface. The thermal system governed the partial differential equations of momentum, temperature and concentration distributions. These partial differential equations are non-dimensionalized first and then treat analytically. Accuracy of solution is carefully confirmed. The involved flow constraints are constructed as function of material constraints, electrical parameter, combined parameter, thermophoretic constraint, convection parameters, effective Prandtl and Schmidt numbers, thermophoresis parameter and Brownian parameter. The results governed by present study can be more effective for enhancement of thermal system. We believed that the present flow model in presence of nanoparticles can be useful to improve the efficiency of thermal energy extrusion system.
