The Ultimate Flow

Ultimate turbulent Taylor-Couette flow.

The flow structure of strongly turbulent Taylor-Couette flow with Reynolds numbers up to Re(i)=2×10(6) of the inner cylinder is experimentally examined with high-speed particle image velocimetry (PIV). The wind Reynolds numbers Re(w) of the turbulent Taylor-vortex flow is found to scale as Re(w)∝Ta(1/2), exactly as predicted by Grossmann and Lohse [Phys. Fluids 23, 045108 (2011).] for the ultim...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

"The ultimate diagnosis".

IN a short article in the British Medical Journal last year, a general practitioner recorded that one day the local postman said to him: "Doctor, most of those who pass away round here are patients of yours." It would certainly be true to say that many of those who have passed away in the Belmont area of Belfast during the past forty years were patients of mine, and this is a matter of mingled ...
