We present the numerical study of unsteady hydromagnetic (MHD) flow and heat trans- fer characteristics of a viscous incompressible electrically conducting water-based nanofluid (containing Al₂O₃ nanoparticles) between two orthogonally moving porous coaxial disks with suction. Different from the classical shooting methodology, we employ a combination of a direct and an iterative method (SOR with optimal relaxation parameter) for solving the sparse systems of linear algebraic equations arising from the FD discretization of the linearized self similar nonlinear ODEs. Effects of the governing parameters on the flow and heat transfer are discussed and presented through tables and graphs. The findings of the present investigation may be beneficial for electronic industry in maintaining the electronic components under effective and safe operational conditions.
