The basis of the doctoral thesis is the analysis of flow and heat transfer of
one or two electrically conducting micropolar fluids in the presence of
magnetic and electric fields. The first part of the dissertation is the
development of mathematical models for described problems of MHD flow
and heat transfer of micropolar fluid, where the research is conducted in
inductionless approximation and for the case of coupled equations. After
that, in the next chapters, the problem of walls conductivity of the channel
is considered, also the effects of induced magnetic field and interface
boundary conditions for the flow of two fluids. Special attention is paid to
the flow of two fluids between inclined plates where one fluid is micropolar
and the other one is Newtonian. Analytical solutions are given for
momentum, microrotation, energy and magnetic induction equations for the
problems of MHD flow of one and two fluids. Next part of the dissertation
has a detailed analysis of phys...ical phenomena that occur in MHD and
EMHD flow of micropolar fluids, and comparison of analytical solutions
obtained in closed form with the results obtained by numerical simulations.
Using the numerical simulations the case of the flow of micropolar fluid in
the horizontal and vertical channels under the influence of magnetic and
electric fields are solved. At the end, within the dissertation detailed
analysis of results are given for micropolar fluids, which is significant in
the technical practices, for different values characteristic dimensionless
numbers that describes MHD and EMHD problems of flow and heat
transfer of micropolar fluids. Special attention is also given to the
applicability of the research in the development of new technologies.
