Flow Field Structure, Characteristics of Thermo-Hydraulic and Heat Transfer Performance Analysis in a Three Dimensions Circular Tube with Different Ball Turbulators Configurations

This paper presents the findings from a research study using computational fluid dynamics (CFD) on impact of different diameter Ball Tabulators Inserts (BTI) three-dimensional flow pattern and heat transfer characteristics within circular tube. analysis was carried under uniform flux conditions with BTI diameters (1, 2, 3, 4, 5, 6, 7, 8 mm). Fluid flow, pressure drop, dynamic pressure, velocity components, thermo-hydraulic, turbulent kinetic energy, viscosity were analysed qualitatively quantitatively. The performance evaluation results revealed that behaviour field contours variations are closely associated configurations. Also, indicated change in near pipe wall around is important parameters for enhancement as compared to obtained without same conditions. Moreover, presented distinguished influence rate transfer. Additionally, vortex through means this kind an parameter use can enhance by more than 46%. Furthermore, maximum value PEF found be 1.03.
