The Effect of Eccentricity in Fully Developed Annular Pipe Flow on Convection Heat Transfer and the Darcy Friction Factor
Eccentricity in annular channels contributes to changes in fluid flow characteristics which in turn, affects the performance and integrity of the configuration. This research investigates a model of an annular channel with a diameter ratio of 0.762, an aspect ratio of 68.9:1 and heating ... Per saperne di più
Coupled Computational Fluid Dynamics (CFD) and Artificial Neural Networks (ANNs) for Prediction of Thermal-hydraulic Performance of Plate-fin-tube Heat Exchangers
Plate fin-tube heat exchangers are used extensively in heating, ventilating, and air conditioning, process engineering, and refrigeration systems. They have a high degree of surface compactness. Substantial heat transfer enhancement is obtained as a result of the periodic starting and ... Per saperne di più
Numerical Study of Secondary Flows in a Sinusoidal Pipe
The direction of the fluid is strongly related to the Reynolds number; as it increases, so does the centrifugal acceleration which tends to push the axial flow towards the outer side of the pipe. Secondary flow appear as 2 or 4 vortical structures after the inflection point. For low ... Per saperne di più
