Unsteady hybrid-nanofluid flow comprising ferrousoxide and CNTs through porous horizontal channel with dilating/squeezing walls

Abstract The key objective of the present research is to examine hybrid magnetohydrodynamics (MHD) nanofluid (Carbon-nanotubes and ferrous oxide–water) CNT – Fe 3 O 4 / H 2 flow into a horizontal parallel channel with thermal radiation through squeezing dilating porous walls. parting motion triggered by walls channel. fluid time-dependent laminar. asymmetric upper lower are distinct in temperature porous. With combination nanoparticles single multi-wall carbon nanotubes, principle exploited. By using similarity transformation, set partial differential equations (PDEs) this mathematical model, governed momentum energy equations, reduced corresponding ordinary (ODEs). A very simple numerical approach called Runge–Kutta system order four along shooting technique used achieve solutions for regulating ODEs. MATLAB computing software create velocity profile graphs various emerging parameters. At end manuscript, main conclusions summarized. Through different graphs, it observed that hybrid-nanofluid has more prominent enhancement than nanofluid. Further, single-wall nanotubes have dominated impact on nanotubes. From calculations, also noted MWCNT water an average 4.84% rate heat transfer SWCNT . On other hand, 8.27% Such study important coolant circulation, inter-body transportation, aerospace engineering, industrial cleaning procedures, etc.
