RISThe Onset of Convection in an Internally Heated Nanofluid Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We analytically studied the onset of convection, induced by internal heating, such as that produced by microwave heating or chemical reaction, in a horizontal layer of a nanofluid subject to Brownian motion and thermophoresis. ...
Convective Instability of the Darcy Flow in a Horizontal Layer With Symmetric Wall Heat Fluxes and Local Thermal Nonequilibrium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear stability of the parallel Darcy throughflow in a horizontal plane porous layer with impermeable boundaries subject to a symmetric net heating or cooling is investigated. The onset conditions for the secondary ...
The Effect of Vertical Throughflow on Thermal Instability in a Porous Medium Layer Saturated by a Nanofluid: A Revised Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The model developed in our previous paper (Nield and Kuznetsov, 2011, “The Effect of Vertical Throughflow on Thermal Instability in a Porous Medium Layer Saturated by a Nanofluid,†Transp. Porous Media, 87(3), pp. ...
An Historical and Topical Note on Convection in Porous Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This note deals with three main themes. The first is a discussion of the early literature on convection in porous media. The second is a brief overview of current analytical modeling of singlephase convection in saturated ...
The Onset of Double Diffusive Convection in a Vertical Cylinder With Vertical Throughflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of vertical throughflow on the onset of convection, induced by an applied vertical temperature gradient in a vertical cylinder is studied analytically using linear stability theory. This problem is important to ...
Forced Convection Past a Rotating Sphere: Modeling Oxygen Transport to a Pond Snail Embryo
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Helisoma trivolvis pond snail embryos are known for their rotation, which is induced by beating of cilia at the embryo's surface. A common hypothesis links this behavior to enhancing oxygen transfer to the embryo's surface. ...
The Effect of Spatially Nonuniform Internal Heating on the Onset of Convection in a Horizontal Fluid Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigated the onset of natural convection in a horizontal fluid layer due to nonuniform internal heat generation, which is relevant to a number of geophysical situations. We investigated a number of ...
Simulating Reversibility of Dense Core Vesicles Capture in En Passant Boutons: Using Mathematical Modeling to Understand the Fate of Dense Core Vesicles in En Passant Boutons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this paper is to use mathematical modeling to investigate the fate of dense core vesicles (DCVs) captured in en passant boutons located in nerve terminals. One possibility is that all DCVs captured in boutons ...
A Numerical Study of Sensitivity Coefficients for a Model of Amyloid Precursor Protein and Tubulin-Associated Unit Protein Transport and Agglomeration in Neurons at the Onset of Alzheimer's Disease
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling of intracellular processes occurring during the development of Alzheimer's disease (AD) can be instrumental in understanding the disease and can potentially contribute to finding treatments for the disease. The ...
Unstable Forced Convection in a Plane Porous Channel With Variable Viscosity Dissipation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fully developed and stationary forced convection in a planeparallel porous channel is analyzed. The boundary walls are modeled as impermeable and subject to external heat transfer. Different Biot numbers are defined at the ...
