The mechanism behind nanofluid to tremendously enhance heat transfer and thermal conductivity due to its widely application in numerious field of biomedical devices and highly advanced technical zones such as cooling of microchips, nano drug delivery, nuclear reaction and radiators etc. To resolve the issues related with high temperature problems and to improve thermal conductivity in practice, nanoparticles soaked into base fluid. A lot of contribution made on nanoparticles which disseminate in base fluid to attain the excellent possible thermal properties 6, 8, 21-22. According to Tiwari et al.21, the suspension of nanoparticles within base fluid alone are not enough. The effect of CNTs six times improved thermal conductivity compared to other nanomaterials 23. The enhancement of various model of CNTs, these tubes have wide range of properties such as thermal and electronic etc 25. Similarly solid nanoparticles preserve high conductivity than liquids. Therefore CNTs is centre of interest for advanced technology due to its electrical and isolated structure. Recent years, different applications of CNTs 24–27 are considered for ideal materials, ranging from ultra-strong fibers to field emission presentations. These tubes have extensive uses and application in various fields like as increased energy density for capacitors, to model structure of catalyst, detection of proteins that specify the existence of oral cancer, gas storage, water purification devices, to detect bacteria in drinking water, to reduce the weight of coaxial cable for aerospace applications, to improve battries for lifetime, extra powerful fiber etc. In this regard, Hayat et al.30 utilized carbon nanotubes in water flow under the homogenous hetrogenous reaction and with melting heat transfer effect. Two different types of CNTs i.e; SWCNT and MWCNT incorporate in water for flow model. It is found that by comparision with other nanofluids minimum thermal resistance and maximum heat transfer conducted while MWCNT suspended in base fluid. Moreover the surface thickness of carbon nanotubes with heat transfer in stagnation point flow examined by Hayat et al. 32.
