Squeeze flow of potato starch gel: effect of loading history on visco-elastic properties
Moutushi Dutta Choudhury, Shantanu Das, Sujata Tarafdar
In this work gelatinized potato starch is shown to retain the memory of past loading history. It exhibits a visco-elastic response which does not depend solely on instantaneous con…
Aggregation Patterns of Salt Crystalizing in Drying Colloidal Solvents
Moutushi Dutta Choudhury, Sayanee Jana, Sruti Dutta +1
We report a study of the structure of droplets of colloidal gels containing dissolved sodium chloride. The components segregate and form intricate patterns. The salt crystalizes in…
Pattern Formation in a Drying Drop of Starch Gel with Sodium Chloride
Moutushi Dutta Choudhury, Sayanee Jana, Sruti Dutta +1
A drop of aqueous potato starch gel with a certain mole fraction of NaCl, when dried on a glass slide, exhibits strong segregation and intricate pattern formation phenomena. The sa…
Spreading of Non-Newtonian and Newtonian Fluids on a Solid Substrate under Pressure
Moutushi Dutta Choudhury, Subrata Chandra, Soma Nag +2
Strongly non-Newtonian fluids namely, aqueous gels of starch, are shown to exhibit visco-elastic behavior, when subjected to a load. We study arrowroot and potato starch gels. When…
Oscillatory Spreading and Surface Instability of a Non-Newtonian Fluid under Compression
Moutushi Dutta Choudhury, Subrata Chandra, Soma Nag +2
Starch solutions, which are strongly non-Newtonian, show a surface instability, when subjected to a load. A droplet of the fluid is sandwiched between two glass plates and a weight…
