Applications
editOne application of the Weber number is for the study of heat pipes. When the momentum flux in the vapor core of the heat pipe is high, there is a possibility that the shear stress exerted on the liquid in the wick can be large enough to entrain droplets into the vapor flow. The Weber number is the dimensionless parameter that determines the onset of this phenomena called the entrainment limit (Webber number greater than or equal to 1). In this case the Weber number is defined as the ratio of the momentum in the vapor layer divided by the surface tension force restraining the liquid, where the characteristic length is the surface pore size.
Pronounciation
editCould do with an IPA pronounciation guide. The name sounds Swiss. Is it said differently to Webber? —DIV (128.250.80.15 (talk) 05:38, 12 April 2008 (UTC))
- Yes, you'd pronounce it more like Veh-ber. Ankid (talk) 15:10, 26 November 2010 (UTC)
