The Significant Effect of Hydromagnetic on Carbon Nanotubes Based Nanofluids Flow and Heat Transfer Past a Porous Stretching/Shrinking Sheet

The 2D steady flow model of carbon nanotubes-based nanofluids and heat transfer past a porous stretchable or shrinkable sheet is studied analytically numerically. A mathematical that governed by system partial differential equations (PDEs) subjected to boundary conditions transformed into dimensionless ordinary (ODEs). non-dimensional ODEs solved using MATLAB bvp4c solver. effect various parameters such as magnetic field, porosity, the stretching/ shrinking velocity parameter, CNTs volume friction on temperature profile, skin friction, Nusselt number rate are investigated numerically results presented graphical illustration. From results, non-unique solutions obtained in cases where shrunk, parameter less than 0.1, porosity 30. Besides, increment field will increase both coefficient, while contrary, decreasing coefficient occur if raised. We also showing SWCNTs more effective compared MWCNTs.
