Abstract
AbstractCarbon nanotubes (SWCNTs/MWCNTs) have widespread applications in micro and nano-electronics, flat panel displays, conductive plastics, gas storage, technical textiles, ultra-capacitors, sensors, biosensor and several others. The shape effects of various kinds of SWCNT/MWCNT nanoparticles share major role in the amelioration of heat transfer rate. The impact of SWCNT/MWCNT nanoparticles’ shapes on the dissipative up and down MHD flow of nanofluids past thin needle subject to second order slip is investigated in the present study. Brick, Cylinder, Platelet and Blade shapes of nanoparticles are taken into consideration. Numerical solution is obtained by R-K method cum shooting technique. The important outcome of this study conveys that heat transfer rate is the lowest for Brick nanoparticles while it is the largest for Platelet nanoparticles.KeywordsUp/down flowMHDSWCNT/MWCNT
