Abstract

Melting heat in mixed convective magnetohydrodynamic flow of viscous material bounded by a stretchable plate is examined. Thermal expression consists of Joule heating and heat generation. Here (γAl₂O₃ − H₂O and γAl₂O₃ − C₂H₆O₂) nanofluids are analyzed. Boundary layer flows is determined for both Prandtl number and effective Prandtl number. Melting heat is accounted. Second law of thermodynamics is utilized to determine entropy generation. Entropy generation is minimized and discussed graphically through different parameters. Furthermore the drag forces and heat transfer rates have been examined through tabulated values.
