Lubrication Theory for Micropolar Fluids

Journal of Applied Mechanics, 1971
The equations governing the flow of a fluid with rigid, spherical substructure are summarized. A two-dimensional flow field is considered and applied to the geometry of a slider bearing. Order-of-magnitude arguments are used which reduce the governing equations to a system of coupled, linear, ordinary differential equations.

Heat-conducting micropolar fluids

Rheologica Acta, 1971
In this paper heat-conducting micropolar fluids are introduced as an extension of the theory of micropolar fluids. Constitutive equations appropriate to describe the thermal and mechanical response of micropolar fluids are constructed. The heat conduction equation is derived and the field equations are obtained. The solution to the problem ofPoiseuille

Convective Wall Plume in Micropolar Fluids

ZAMM, 1998
Summary: A boundary layer analysis is presented to study the steady-state free convection arising from a line thermal source located at the leading edge of a vertical adiabatic surface embedded in a micropolar fluid. Nonsimilar solutions based on the finite difference method are presented for the velocity, angular velocity, and temperature fields.

Microchannel fluid behavior using micropolar fluid theory

Proceedings MEMS 98. IEEE. Eleventh Annual International Workshop on Micro Electro Mechanical Systems. An Investigation of Micro Structures, Sensors, Actuators, Machines and Systems (Cat. No.98CH36176), 2002
In this paper, we describe microchannel fluid behavior using a numerical model based on micropolar fluid theory and experimentally verify the model using micromachined channels. The micropolar fluid theory augments the laws of classical continuum mechanics by incorporating the effects of fluid molecules on the continuum.

Micropolar fluids with stretch

International Journal of Engineering Science, 1969
Abstract Equations of motion, constitutive equations, and boundary conditions are derived for a class of micropolar fluids which can stretch or contract. These fluids respond to intrinsic rotational motions and spin inertia and therefore can support couple stress and body couples.

Thermodynamics of micropolar Bingham fluids

Journal of Non-Newtonian Fluid Mechanics, 2016
Abstract Starting from the basic thermodynamic principles, we derive equations of micropolar Bingham fluids allowing for the variable concentration of polar particles. On the one hand, such fluids exhibit couple stresses, a non-symmetrical stress tensor, microrotations, and microinertia. On the other hand, the fluids support a yield stress.

Magnetoconvection in a micropolar fluid

International Journal of Engineering Science, 1998
Abstract The problem of Rayleigh–Benard convection in an electrically conducting micropolar fluid layer permeated by a uniform, vertical magnetic field is investigated with free–free, isothermal, spin-vanishing boundaries. The influence of the various micropolar fluid parameters and magnetic field on the onset of stationary convection has been ...

Couette flow of micropolar fluids

International Journal of Engineering Science, 1968
Abstract An application of Eringen's theory[1–3] or micro-polar fluids has been made to the problem of Couette flow. These fluids respond to micro-rotational motions and spin inertia and can therefore support couple stress and distributed body couples. An exact solution to the system of governing equations is given in a simple closed form. When micro-

Micropolar and dipolar fluids

International Journal of Engineering Science, 1968
Abstract The theories of micropolar and dipolar fluids have been reviewed briefly and application of these theories to the problem of Poiseuille flow in a circular channel is discussed.
