WebMar 29, 2024 · Commercial water tunnels typically generate a momentum thickness based Reynolds number (Reθ) ∼1000, which is slightly above the laminar to turbulent transition. The current work compiles the literature on the design of high-Reynolds number facilities and uses it to design a high-Reynolds number recirculating water tunnel that spans the … WebThe Reynolds number is a dimensionless number. High values of the parameter (on the order of 10 million) indicate that viscous forces are small and the flow is essentially inviscid. The Euler equations can then be used …

WebJun 1, 2024 · A high Reynolds number (usually above 4000) indicates the flow is turbulent. Turbulent flow results in a convective heat-transfer coefficient (between the cooling-channel wall and the coolant) that is an order of magnitude greater than that of a laminar flow. Simply put, for the same temperature difference, a turbulent flow can transfer heat at ... WebAug 24, 2024 · The Reynolds number has to be so high, in fact, that turbulence doesn't have the physical mechanism it needs to form (viscosity). These kinds of confusions crop up all the time when learning about ideal (or potential) flows.
