Velocity and pressure fluctuations on inclined tube banks submitted to turbulent flow

Velocity and pressure fluctuations on inclined tube banks submitted to turbulent flow

This paper presents the experimental study of pressure and velocity fluctuations and their interdependence, in the turbulent flow impinging on arrangements of yawed circular cylinders simulating inclined tube banks with square arrangement and a pitch to diameter ratio of 1.26. Measurements were performed with hot-wires and a pressure transducer. Behaviour of fluctuating quantities is described ...

Wall-pressure Fluctuations and Pressure-velocity Correlations in Turbulent Boundary Layers

Investigation on Turbulent Nanofluid Flow in Helical Tube in Tube Heat Exchangers

In this study, the thermal characteristics of turbulent nanofluid flow in a helical tube in the tube heat exchanger (HTTHE) were assessed numerically through computational fluid dynamics (CFD) simulation. The findings of both the turbulent models: realizable k-epsion (k-ε) and re-normalisation group (RNG) k-epsilon were compared. The temperature distribution contours show that realizable and RN...
