The paper deals with separation of a nominally steady and two-dimensional incompressible boundary layer from the smooth surface of a rigid blunt body in the presence of a front stagnation point, here denoted by PF . In agreement with earlier studies on the flow past a bluff body, it is argued that in the limit of vanishing viscosity, i.e. in the limit where the globally defined Reynolds number ...

This review surveys the dramatic variations in wake structures and flow transitions, addition to body forces, that appear as motion of bluff bodies through a fluid occurs increasingly closer solid wall. In particular, we discuss two cases translating parallel walls at varying heights impacting on walls. former case, highlight changes varies from an isolated or very close wall, including effects...

Abstract In this paper, we present a Hamiltonian and thermodynamic theory of heat transport on various levels description. Transport is formulated within kinetic polarized phonons, unpolarized hydrodynamics phonons. These description are linked by Poisson reductions, where no linearizations made. Consequently, obtain new phonon that contains convective terms dependent vorticity the flux, which ...

Fully turbulent flow was used in the study and sm...
