Pipe flows
Webb1 juni 2010 · The popular RANS models: k – ε, k – ω, Reynolds stress model (RSM), and the Large Eddy Simulation are selected to model fully-developed turbulent flow through rib roughened pipes. The Reynolds-averaged Navier–Stokes equations govern the transport of the averaged flow quantities, with the whole range of the scales of turbulence being ... Webb14 feb. 2024 · Numerical simulations of laminar pipe and channel flows were carried out: (i) to understand the effect of inlet conditions, viz., flat inlet and streamtube inlet, on entry lengths, and (ii) to investigate the flow development in radial/transverse locations. Results show that hydrodynamic entry lengths from the streamtube inlet simulations are …
