Natural convection of micropolar fluid in an enclosure with boundary element method

Onset of Bénard–Marangoni convection in a micropolar fluid

“…The governing equations, which describe the system behavior are conservation of momentum, microrotation and energy, are given below in terms of the stream function W as (see for instance [19]): …”

Natural convection in a shallow cavity filled with a micropolar fluid

“…The governing equations which describe the system behaviour are conservation of momentum, microrotation and energy which are given below in terms of the stream function W 0 as (see for instance [12])…”

“…Various boundary conditions, for microrotation, were considered and they were found to have a significant influence on the heat transfer. Natural convective flow and heat transfer of micropolar fluids confined in a square cavity, subject to various thermal conditions, was investigated numerically by Aydin and Pop [10,11] and Zadravec et al [12]. In all these studies it was demonstrated that the microrotation of particles in suspension in general decreases the overall heat transfer.…”

Transient buoyancy-opposed double diffusive convection of micropolar fluids in a square enclosure

“…They solved the governing equations using the Optical Homotopy Asymptotic Method (OHAM), and observed that with the increase in the Reynolds number, there is an increase in the stream-wise and transverse velocities. Zadravec et al [23] have studied the natural convection of a micropolar fluid in an enclosure with the boundary-element method to derive the governing equations in differential and integral forms. They observed that the local and average Nusselt numbers decrease as the micropolar material parameter increases.…”
