Non-aligned stagnation point flow of radiating Casson fluid over a stretching surface

open access: yesAlexandria Engineering Journal, 2018
This paper intends to inspect the combined influence of mixed convection and thermal radiation on non-aligned Casson fluid over a stretching surface. Using scaling transformations, the governing partial differential equations are converted into a set of ...

OHAM analysis of Newtonian heating in mixed convective flow of CNTs over a stretched cylinder

open access: yesAlexandria Engineering Journal, 2022
This work reports mathematical modeling and analysis of mixed convection flow of nanofluids with stagnation point by a stretching cylinder. Carbon nanotubes are dispersed as nanomaterial in the baseliquid of water.

Convergence of adaptive mixed finite element method for convection-diffusion-reaction equations [PDF]

open access: yes, 2013
We prove the convergence of an adaptive mixed finite element method (AMFEM) for (nonsymmetric) convection-diffusion-reaction equations. The convergence result holds from the cases where convection or reaction is not present to convection-or reaction ...

Vortex structure and small scale characteristics in turbulent Rayleigh–Bénard convection with mixed isothermal–adiabatic bottom boundary

open access: yesAIP Advances, 2023
Turbulent Rayleigh–Bénard convection with a mixed isothermal–adiabatic bottom boundary is simulated to investigate the effect of a nonideal thermal boundary on vortex structure and small-scale characteristics in turbulent convection.

Entropy generation and induced magnetic field in pseudoplastic nanofluid flow near a stagnant point

open access: yesScientific Reports, 2021
In this present article the entropy generation, induced magnetic field, and mixed convection stagnant point flow of pseudoplastic nano liquid over an elastic surface is investigated. The Buongiorno model is employed in modeling.

Numerical Analysis of Turbulent Mixed Convection in Vertical Annular Channel

open access: yesYuanzineng kexue jishu, 2023
Reactor cavity cooling system (RCCS) is a competitive residual heat removal scheme for small modular reactors. In this paper, the RCCS has been simplified to a scenario that ascending air flow is got heated in vertical annular channels and driven by ...

Analysis of instability patterns in non-Boussinesq mixed convection using a direct numerical evaluation of disturbance integrals [PDF]

open access: yes, 2009
The Fourier integrals representing linearised disturbances arising from an initially localised source are evaluated numerically for natural and mixed convection flows between two differentially heated plates. The corresponding spatio-temporal instability

Convective Boundary Mixing Processes

open access: yesResearch Notes of the AAS, 2022
Abstract Convective motions extend beyond the nominal boundaries of a convection zone. These motions mix fluid through multiple mechanisms collectively called “convective boundary mixing.” In this note, we discuss three distinct fluid dynamical processes: convective overshoot, entrainment, and penetrative convection.

Thermal and solutal stratification in mixed convection three-dimensional flow of an Oldroyd-B nanofluid

open access: yesResults in Physics, 2017
This paper investigates the double stratified effects in mixed convection three-dimensional flow of an Oldroyd-B nanofluid. The flow is due to a bidirectional stretching surface.

Biomass gasification for syngas and biochar co-production: Energy application and economic evaluation [PDF]

open access: yes, 2018
Syngas and biochar are two main products from biomass gasification. To facilitate the optimization of the energy efficiency and economic viability of gasification systems, a comprehensive fixed-bed gasification model has been developed to predict the ...
