Impact of hybrid nanofluids (Ag‐ <scp> TiO ₂ </scp> / <scp> H ₂ O </scp> ) on improving the performance of a heat exchanger with turbulent induction elements

In this article, the optimization of a twisted strip heat exchanger was explored aiming at enhancing transfer. To end, governing equations using ANSYS-FLUENT software and nanofluid flow k-ε RNG turbulence model were simulated in exchanger, respectively. The investigated parameters included temperature, pressure, velocity, kinetic energy (TKE), concentration, shape factor, Reynolds number, diameter spherical obstacle on tape. addition, applied nanoparticles Ag TiO2, which combined as hybrid with ratio 50%–50%. Investigations surface tape revealed reduction temperature while an increase pressure changes, TKE. Moreover, it specified that application lamina-shaped (non-spherical) has maximum convection transfer coefficient relative to platelets shapes. highest rate achieved concentration ϕ = 0.06 . Based findings, upgraded by increasing number such gained 18,000. Finally, enhanced approximately 52% obstacles from 3 12 mm.
