Design and Analysis for Heat Transfer Through Twisted Tape with Nanoparticles

Different techniques have been used to achieve a high heat transfer rate. Among them, one of the advanced is suspension nanoparticles in base fluids as water and coated with aluminum titanium. The present work has carried out on double pipe exchanger twisted tape insert twist ratio (y/w = 4 6) thickness (0.8mm) for investigation nanofluid counter flow arrangement under turbulent conditions. computational fluid dynamic code simulates different concentrations (0.01% 0.19%) ANSYS FLUENT R 18.1 software. overall coefficients all are measured function hot cold stream's mass rates. thermal performance parameter coefficient compared nanofluids water. concludes that there good enhancement rate using nanofluid.
