Problem by constitute a liquid in fluent

BaDaBoOm · June 28, 2014, 15:06

Hey Guys,

as a project for studiing i construct a tank filling system. As Model I choose eulerian with two Phases (fuil and air). The Densety of oil is 840 kg/m³ and the viscosity 0,504 kg/m*s. The Massflow is located between 3 and 13 Liter/sec, so reynolds is under 600 (laminar)
The Problem is, it don´t look like a Liquid, but rather like a gas flow. Maybe i forget just to make some settings. Maybe one of you guys can help me ;-)

hey one problem was a false viscosity (Oil= 0.00504 kg/m*s ist correct). As a consequence it is not laminar. -> k-epsilon or k-omega. But it still not look like a liquid :-(

Problem solved :-) Model should be Volume of Fluid und I have to use Mass flux
