Entropy generation in nanofluid flow due to double diffusive MHD mixed convection.

This work is concerned with the numerical study of laminar, steady MHD mixed convection flow, and entropy generation analysis of -water nanofluid flowing in a lid-driven trapezoidal enclosure. The aspect ratio of the cavity is taken very small. The cavity is differentially heated to study the fluid flow, heat, and mass transfer rate.

Numerical simulation of MHD double diffusive natural convection and entropy generation in a wavy enclosure filled with nanofluid with discrete heating.

A numerical investigation of entropy generation, heat and mass transfer is performed on steady double diffusive natural convection of water-based AlO nanofluid within a wavy-walled cavity with a center heater under the influence of an uniform vertical magnetic field. The top horizontal wavy wall, left and right vertical walls of the enclosure are kept at low temperature and concentration of and whereas central part of the bottom horizontal wall is maintained at high temperature and concentration of and and the remaining part is kept adiabatic where temperature and concentration gradient are taken as zero. The Bi-CGStab method and Tri-diagonal algorithm are used to solve the governing equations.
