Preparation and Rheological Characterization of Water-Soluble Boger Fluids
The primary focus of the study is to prepare and characterize water-soluble Boger fluids as they offer improved handling characteristics. The fluids have been prepared in the concentration range of 0.02–0.05 % (wt/vol.) Polyacrylamide (PAA) in a mixture of 80 % glycerol and 20 % distilled water by volume. Dynamic and steady shear data are represented in the temperature range of 15–35 °C. The shear mode data were fitted to power law model to calculate the flow consistency index (K) and flow behavior index (n). With increase in PAA concentration, the fluid character shifts from Boger to shear thinning viscoelastic fluid. Fluid relaxation time (λ) was calculated by fitting the oscillatory data to four mode Maxwell model. Empirical equations for the prediction of K, n, and λ are proposed by incorporating simultaneous effect of polymer concentration and temperature. Presented data could be of great use in unit operations such as fixed and fluidized beds dealing with Boger fluids.
期刊介绍：
Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
