Theorems on shear-free perfect fluids with their Newtonian analogues

, 1997
In this paper we provide fully covariant proofs of some theorems on shear-free perfect fluids. In particular, we explicitly show that any shear-free perfect fluid with the acceleration proportional to the vorticity vector (including the simpler case of ...

Nonlinear Fluid Dynamics Description of non-Newtonian Fluids

, 2004
Nonlinear hydrodynamic equations for visco-elastic media are discussed. We start from the recently derived fully hydrodynamic nonlinear description of permanent elasticity that utilizes the (Eulerian) strain tensor.

Ionic Liquid‐Enhanced 3D Printed Flexible Resin for Pressure‐Sensing Applications

Advanced Materials Technologies, EarlyView.
A 3D‐printed resin–ionic liquid (IL) composite forms gyroid ionotronic architectures showing dynamic ionic migration under compression. Impedance analysis reveals distinct frequency responses across three topologies at high IL concentrations.

Bipolar Barotropic Non-Newtonian Compressible Fluids [PDF]

ESAIM: Mathematical Modelling and Numerical Analysis, 2000
Summary: For a barotropic motion of non-Newtonian bipolar fluids, we consider a special case where the stress tensor is expressed in the form of potentials depending on \(e_{ii}\) and \(({\partial e_{ij} \over \partial x_k})\). We prove the asymptotic stability of the rest state under the assumption of regularity of potential forces.

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

Post-Newtonian cosmological dynamics of plane-parallel perturbations and back-reaction

, 2011
We study the general relativistic non-linear dynamics of self-gravitating irrotational dust in a cosmological setting, adopting the comoving and synchronous gauge, where all the equations can be written in terms of the metric tensor of spatial hyper ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
