Estimation of heat transfer coefficient and friction factor with showering of aluminum nitride and alumina water based hybrid nanofluid in a tube with twisted tape insert

Here, the twisted tape inserted in tube for hybrid nanofluid containing an alumina nitride \(AIN\) and alumina oxide \({\text{Al}}_{2} {\text{O}}_{3}\) nanopowders with 30 nm diameter size is considered. The twisted tape is inserted in full length of tube. In this analysis, the 3D, \(AIN – {\text{Al}}_{2} {\text{O}}_{3} /{\text{water}}\) hybrid nanofluid flow with steady state condition problem is formulated. In the current advanced research the range of Reynolds number 800, 1200, 1600 and 2000 considered. Figure 1 indicates the flow geometry tube with twisted tape. The dimensions of…
