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.

Numerical approach for chemical reaction and suction/injection impacts on magnetic micropolar fluid flow through porous wedge with Hall and ion-slip using Keller Box method

Waves in Random and Complex Media, 2021
In the present investigation, influence of the chemical reaction, magnetic field and slip on micropolar fluid flow via a porous wedge in the existence of Hall and ion-slip are examined. The pertinent highly non-linear PDEs are changed into an arrangement

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 ...
