| Özet |
| This study focuses on investigating the thermal performance of elliptical tubes in heat transfer applications with three different working fluids, namely water, CuO-water nano fluid, and Al2O3-water nano fluid. The research emphasizes the role of channel cross-sectional geometry and the utilization of nano fluids in enhancing heat transfer for four different elliptical aspect ratios with the same hydraulic diameter. To ensure fully developed hydrodynamic flow conditions and eliminate pipe outlet effects, a test section for flow analysis was identified at the midsection of the designed pipe geometry. Numerical simulations were conducted using ANSYS 2020 R2 commercial software for low Reynolds numbers, which yield laminar flow, to analyze the impact of the elliptical cross-sectional geometry and heat transfer characteristics on the flow. The effects of nano fluids and the use of elliptical pipes on heat transfer were … |
