Stability analysis of dual solutions magnetohydrodynamics stagnation-point flow of Carreau fluid towards a stretching/shrinking surface with induced magnetic field and convective boundary conditions

open access: yes, 2020
The problem of the steady two-dimensional magnetohydrodynamics (MHD) stagnation-point flow of Carreau fluid towards a permeable stretching/shrinking sheet is studied. The effect of the induced magnetic field and convective boundary conditions are taken

KKL-model of MHD CuO-nanofluid flow over a stagnation point stretching sheet with nonlinear thermal radiation and suction/injection

open access: yesResults in Physics, 2018
In this study, we analyzed numerically the effects of magnetic field and thermal radiation on forced-convection flow of CuO-water nanofluid past a stretching sheet with stagnation point in the presence of suction/injection.

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Free convection boundary layers driven by exothermic surface reactions: critical ambient temperatures

open access: yes, 1995
A model for the free convection boundary-layer flow near a forward stagnation point driven by heating from a surface on which there is a catalytic reaction is discussed.

High-speed flow with discontinuous surface catalysis [PDF]

open access: yes, 2000
In a reacting gas flow both gas-phase chemical activity and surface catalysis can increase the rate of heat transfer from the gas to a solid surface. In particular, when there is a discontinuous change in the catalytic properties of the surface, there ...

Thermally stratified flow of second grade fluid with non-Fourier heat flux and temperature dependent thermal conductivity

open access: yesResults in Physics, 2018
This attempt explores stagnation point flow of second grade material towards an impermeable stretched cylinder. Non-Fourier heat flux and thermal stratification are considered. Thermal conductivity dependents upon temperature.

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization

open access: yesAIChE Journal, EarlyView.
Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...
