# Fluids Database

Non-Newtonian / non-settling liquids' properties are entered directly into the Fluids Database via the Fluid Editor fields shown below. The Fluid Editor dialog is selected via the 'Database | Fluids...' menu item. FLUID EDITOR
Field Name | Field Entry | Image
Fluid Type | Select Non-Newtonian Liquid |
Fluid Name | Enter a unique name |
Liquid Viscosity Definition | Select to go to the Physical Property Editor |
Notes: 1.All other fields are defined in the Database Section: Fluids. 2.The physical properties of the fluid are entered via the Physical Properties Editor, which activates when the Liquid Viscosity Definition is selected. PHYSICAL PROPERTY EDITOR - LIQUID VISCOSITY
Field Name | Field Entry | Image
Viscosity Definition | Select from: Undefined Directly define constants Shear Stress-Shear Rate |
If 'Directly define constants' is selected then .. Fluid Class | Select from: Casson Power Law Herschel Bulkley Bingham Plastic |
If 'Shear Stress-Shear Rate' is selected then ... Table | Enter tabular data for curve fit |
From the above table you can see that fluid viscosity as a function of shear can be stored as table values of stress against shear OR you can enter the relevant model constants directly according to the rheology selected. The main reason for not allowing data entry directly from say rotating cup or tube viscometers is because of the individual correction factors that need to be applied to the direct measurements.
