The Fluid Flow in the T-Junction. The Comparison of the Numerical Modeling and Piv Measurement

Numerical study of convective heat transfer in T‐bifurcating channel

“…Its magnitude has been observed to be mostly between 1% and 4 % of the bulk mean velocity in most straight ducts with a noncircular cross section, but the effects on wall shear stress distribution and heat transfer rates are quite significant. The defect of the first‐order models is shown being fatal in square‐duct flows where the secondary flow normal to the axis of a duct is induced . So, some form of Reynolds stress modeling is usually required in order to calculate this type of secondary motion.…”

“…The defect of the first-order models is shown being fatal in square-duct flows where the secondary flow normal to the axis of a duct is induced. 8,13 So, some form of Reynolds stress modeling is usually required in order to calculate this type of secondary motion. The second-order models have the potential of properly expressing strong anisotropy of turbulence.…”

PIV investigations on the turbulent mixing of two opposing flows inside a scaled chimney model of a research reactor

“…An analytical study was reported by El-Morshdy which was based on a steady, incompressible, irrotational flow in two-dimensional geometry with zero inclination between the central chimney & outlet nozzle. However, the mixing of fluid flows in T-junction and X-junction was reported by various researchers [3][4][5][6][7][8][9]. Here T-junction allows incoming fluid streams to be combined into one outlet.…”

“…Steady state 3-dimensional CFD simulations were carried out to predict the mean velocity and mean temperature using standard j-e turbulence model which were found to be in good agreement with the measurements. Fluid flow simulation in a T-junction (with 90°a ngle and 50 mm diameter of each branch) was done by Stigler et al [9] using both numerical modelling and PIV measurement.…”

Characteristics of the pipe junction with 2.4 cross-section area ratio for the case of the flow division

“…For example numerical study of fluid flow has been presented in the [7,8]. The PIV measurement of the fluid flow in the pipe junction has been described in [9] The Comparison of the PIV measurement with numerical solution of fluid flow in [10]. The first new characteristics obtained by measuring and its comparison with CFD calculations were presented at [11].…”
