Overview: The WinRheo II software is designed for the rheological evaluation and presentation of data from GÖTTFERT Capillary Rheometers. It supports data from both laboratory devices like RHEOGRAPH and Rheo-Tester, as well as online devices such as RTR/RTS-TD, SSR, or MBR through ROSWin software. The integration with MS-Excel allows for extensive data evaluation and graphical representation.

Modules Implemented:

• Rheological Corrections: Includes Rabinowitsch-Weissenberg, Bagley (linear and non-linear), Mooney (wall slip), heat dissipation, and Hagenbach, Gleissle corrections.
• Models: Supports Ostwald-de Waele (power law), Münstedt, Carreau–Winter, Cross, Sabia, and Yasuda models.
• Temperature Shift: Features Arrhenius, WLF, Carreau-WLF, Carreau-Arrhenius, Cross-WLF, and Cross-Arrhenius models.
• Various Calculations: Includes normal stress difference, elongational viscosity to Cogswell, and NNI coefficient (non-Newtonian-index).
• Calculations for Options: Offers die swell, PVT calculations for isobar and isothermal diagrams, counter pressure chamber, thermal conductivity, and analysis of flow instabilities (the latter two require external modules).
