Superchaotropic Nano‐ion Binding as a Gelation Motif in Cellulose Ether Solutions
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 Nano‐ions, like polyoxometalates and boron clusters, co‐assemble strongly with non‐ionic solutes in water driven by the chaotropic effect. Here, nano‐ion assembly with non‐ionic cellulose ethers (CE) is shown to result in unprecedented thickening effects and gelation of CE‐solutions. An interplay of electrostatic repulsion and attraction between chains

Post-Newtonian non-equilibrium kinetic theory [PDF]
Annals of Physics 441 (2022) 168865, 2021 The post-Newtonian hydrodynamic equations for a non-perfect fluid are developed within the framework of a post-Newtonian Boltzmann equation. The post-Newtonian components of the energy-momentum tensor are determined by considering the relativistic Eckart decomposition for a viscous and heat conducting fluid.

Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations
Chemical Engineering &Technology, Volume 46, Issue 1, Page 29-36, January 2023., 2023 An efficient dynamic friction model based on the Stribeck curve is presented, which allows to investigate the influencing parameters on the stick‐slip effect through finite element simulations. The simulation of a tribometer test proofs that the model correlates well with the tribometer test results.

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 334-351, February 2023., 2023 A boundary‐conforming free‐surface finite element method applied to fused deposition modeling (FDM) is presented. Using a boundary‐conforming approach shows to have several advantages in an FDM simulation. In particular, boundary conditions, like heat fluxes or free‐surface, can be directly imposed on the boundary.

A collision result for both non-Newtonian and heat conducting Newtonian compressible fluids [PDF]
, 2023 We generalize the known collision results for a solid in a 3D compressible Newtonian fluid to compressible non-Newtonian ones, and to Newtonian fluids with temperature depending viscosities.

Generalized reynolds number for non-newtonian fluids [PDF]
Progress in Propulsion Physics, 2009 An extended version of the generalized Reynolds number was derived to characterize the duct flow of non-Newtonian gelled fluids of the Herschel-Bulkley-Extended (HBE) Type. This number allows also estimating the transition from laminar to turbulent flow conditions.

Heat Transfer, Volume 52, Issue 1, Page 395-429, January 2023., 2023 Abstract The significance of hybrid nanofluids in controlling heat transmission cannot be overemphasized. Therefore, this article scrutinizes the electromagnetized flow of Carreau hybrid nanofluid towards a stretching surface in a Darcy–Forchheimer porous medium with the occurrence of slip conditions.
