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…

Magnetic Knots Push Future Computing Toward 3D
Knots in magnetic materials may provide a new direction for next-generation computing architectures to branch out into. To that end, researchers have now created a novel magnetic knot that looks like a tiny magnetized version of a cinnamon twist. And this same magnetic knot—embedded in a magnetic material a little like an electron hole is…
