Hersey numberとは
WitrynaHersey is both a surname and a given name. Notable people with the name include: Surname: David Hersey (born 1939), American lighting designer; Derek Hersey … WitrynaAlternatively, the Hersey number is the dimensionless number obtained from the velocity (m/s) times the dynamic viscosity (Pa∙s = N∙s/m2), divided by the load per unit length of bearing (N/m). Thus, for a given viscosity and load, the Stribeck curve shows how friction changes with increasing velocity.

In the design of fluid bearings, the Sommerfeld number (S) is a dimensionless quantity used extensively in hydrodynamic lubrication analysis. The Sommerfeld number is very important in lubrication analysis because it contains all the variables normally specified by the designer. The Sommerfeld number is named after Arnold Sommerfeld (1868–1951). Witryna1: Stribeck curve as a function of the Hersey number H.
