3D numerical analysis of natural convection and entropy generation within tilted rectangular enclosures filled with stratified fluids of MWCNTs/water nanofluid and air

摘要

Highlights?Natural convection and entropy generation within a 3D enclosure.?Fluid flow, heat transfer and irreversibility study within an enclosure filled with two immiscible fluids of air/nanofluid.?Analysis of the effects of tilt angle in enclosures on their heat transfer performances.?Tilt angle is a useful method to control the heat transfer rate and entropy generation.?3D solution renders comprehensive view of natural convection phenomenon.AbstractTo obtain reliable results of natural convection phenomenon for stratified systems in the three-dimensional enclosures which are trendy in the industries, it must be analyzed in 3D form. The three-dimensional natural convection within the enclosures filled with two stratified and immiscible fluid
