Das Sutherland-Modell beschreibt die Temperaturabhängigkeit der Viskosität von Gasen. Es wurde 1893 von dem australischen Physiker William Sutherland vorgeschlagen. Das Modell basiert auf der kinetischen Gastheorie, wobei zur Beschreibung der intermolekularen Wechselwirkungen ein stark idealisiertes Wechselwirkungspotential verwendet wird. Trotz der verwendeten groben Näherungen insbesondere bei dem verwendeten Wechselwirkungspotential reproduziert das Mo… SpletViscosidade dinâmica do fluido - (Medido em pascal segundo) - A viscosidade dinâmica do fluido é a medida de sua resistência ao fluxo quando uma força externa é aplicada.
