VIS - Mixture Viscosities
While the pure component property data bank DDB-PURE contains approx. 128,432 viscosity data points for more than 3,769 components and has been intensively used for the development of a reliable estimation method for liquid viscosities, no mixture viscosities were available in the DDB up to recently. Knowledge of the viscosity, especially in case of liquids is of great importance for selecting the right operating conditions in process synthesis. Numerous customers have inquired about experimental data and estimation methods in the past. DDBST therefore has started to build up a data bank for mixture viscosities and is proud to present the first version as part of DDB 2010. DDB-VIS contains 10,959 data sets with approx. 129,560 data points (appr. 97% for the liquid and 3% for the vapor phase) for dynamic and kinematic viscosities of mixtures. There are appr. 2,850 binary data sets ( 2,850 data points), 218 ternary data sets ( 218 data points), 13 datasets for quaternary and 8 datasets for higher systems. (Version 2011). In general, dynamic viscosities are about 10 times more frequent than kinematic viscosities. As in case of most data banks, there are some systems for which an especially large amount of data is available:
The data bank contains dynamic viscosities for 3,089 different mixtures. Concerning price and license options, please email to inquiry@ddbst.com. |
