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…
Spreading of Fluids on Solids Under Pressure: Effect of Slip
Soma Nag, Tapati Dutta, Sujata Tarafdar
Spreading of different types of fluid on substrates under an impressed force is an interesting problem. Here we study spreading of four fluids, having different hydrophilicity and…
Fracture of Composites: Simulation by a Spring Network Model
Supti Sadhukhan, Tapati Dutta, Soma Nag +1
Composite materials are often stronger than their constituents. We demonstrate this through a spring network model on a square lattice. Two different types of sites (A and B) are d…
Scaling Laws for Spreading of a Liquid Under Pressure
Soma Nag, Suparna Dutta, Sujata Tarafdar
We study squeeze flow of two different fluids (castor oil and ethylene glycol) between a pair of glass plates and a pair of perspex plates, under an applied load. The film thicknes…
