WebMar 30, 2024 · Results show the features of this model alone rather than a fit to present data. The model's balance is between convection and the form of the continent, including self-adjustment of its thickness and length. The model involves the convection of a fluid with a compositional variation making light fluid float on top of simple convection. Model fitting can support both practical applications (performance predictions and processability) of your measurements and as an investigative tool (complex structure formation, formulation, etc.). A few common model fittings/ corrections used for viscosity measurements are: Cross Model Carreau-Yasuda Model Power Law Arrhenius Model
