The investigation of twisted tape inserted into a tube. Twisted tape, available in laminar, transitional, and turbulent flow regimes, is made of flat metal strips or pieces twisted into a pattern with regular spacing. Nanoparticle volume fractions and Reynolds numbers were tested, with 0–3% and 500–3500 ranges, respectively. The analysis uses nanofluids (CuO and Al2O3) with water to present the changing thermal and fluidic behavior among the tubes having fixed lengths. These profiles’ effects on heat transfer coefficient, Nusselt number, and Frictional Coefficient variations with Reynolds number are discussed over this tape, and the results are presented comparatively. The SIMPLE Algorithm, finite volume method (FVM), and Second Order Upwind Difference Scheme (SOUDS) are utilized for discrete governing equations. The CuO/water nanofluid improved the heat transfer properties. Higher Reynolds numbers resulted in an increase in the Nusselt number, while lower Reynolds numbers resulted in an 11.01% increase.

摘要

The investigation of twisted tape inserted into a tube. Twisted tape, available in laminar, transitional, and turbulent flow regimes, is made of flat metal strips or pieces twisted into a pattern with regular spacing. Nanoparticle volume fractions and Reynolds numbers were tested, with 0–3% and 500–3500 ranges, respectively. The analysis uses nanofluids (CuO and Al2O3) with water to present the changing thermal and fluidic behavior among the tubes having fixed lengths. These profiles’ effects on heat transfer coefficient, Nusselt number, and Frictional Coefficient variations with Reynolds number are discussed over this tape, and the results are presented comparatively. The SIMPLE Algorithm, finite volume method (FVM), and Second Order Upwind Difference Scheme (SOUDS) are utilized for discrete governing equations. The CuO/water nanofluid improved the heat transfer properties. Higher Reynolds numbers resulted in an increase in the Nusselt number, while lower Reynolds numbers resulted in an 11.01% increase.
