On the role of momentum tensions in micropolar ferrohydrodynamics

N.F. Patsegon , I. Ye. Tarapov

The steady flows with straight stream lines of micropolar ferrofluid are considered. The tangential discontinuities appearing in such flows of partially dissipative ferrofluid are studied. It is illustrated that momentum tensions (couple stress) are of primary importance in the investigation of those discontinuities and in constructing solutions in the regions of large gradients of constitutive parameters. The solution of Poiseuille's problem in micropolar ferrohydrodynamics is obtained and analysed.
