DIAGNOSIS OF STEADY-STATE CHARACTERISTICS IN LAMINAR FLOW OF FLUIDS

Rudarsko-geološko-naftni Zbornik
Laminar flow of fluids is one of the most common forms of motion in oilfield practice. In such a flow regime of fluid, the determination of velocity-flow rate performance which takes into account the rheological properties of the fluid is of great ...

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Ohmic heating dominates and ultrasound modulates aquafaba structure: A combined approach to design stable plant‐based emulsions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study investigated the individual and combined effects of ohmic heating (OH, 20 and 40 V cm−1) and ultrasound (US, 425 and 850 W) on the chemical, physicochemical, and technological properties of chickpea aquafaba (AF) and its emulsions.

Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

Macromolecular Rapid Communications, EarlyView.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.

Thermal Planar and Radial Free Jets for An Ostwald‐de Waele Fluid With Shear‐Rate Dependent Thermal Diffusivity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The planar and radial thermal free jets for forced convection of a non‐Newtonian power‐law fluid are investigated. The thermal diffusivity is dependent on the shear‐rate and is not a constant. The flow in planar and radial thermal free jets is governed by the momentum, continuity and energy balance equations. In the stream‐function formulation,

CONVENTIONAL PRESSURE ANALYSIS FOR NATURALLY-FRACTURED RESERVOIRS WITH NON-NEWTONIAN PSEUDOPLASTIC FLUIDS

Revista Fuentes El Reventón Energético, 2013
Conventional oil reserves are coming to an end, then, some unconventional sources, such as heavy oil, are being the aim of oil companies. Most of heavy oils, drilling fluids and fracturing fluids behave as non-Newtonian and these fluids are erroneously ...

Particle settling in a shear-thinning, viscoelastic fluid in the presence of wall effects

Scientific Reports
The settling of particles in fluids is a widespread phenomenon and commonly involves accounting for the effects of walls. Particle settling and wall effects are well understood for Newtonian fluids but the consequences of non-Newtonian fluid properties ...

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.
