This work aimed to analyze the heat transfer of micropolar fluid flow in a constricted channel influenced by thermal radiation and Lorentz force. A finite difference-based solver, on Cartesian grid, is used for numerical solution after transforming governing equations into vorticity-stream function form. The impact various emerging parameters wall shear stress, axial velocity, micro-rotation ve...

To study the natural convection and entropy generation of a semicircular cavity containing heat source under magnetic field, based on single-phase lattice Boltzmann method, closed model with in upper (Case 1) lower 2) is proposed. The filled CuO-H2O nanofluid, hot placed center cavity. effects Rayleigh number, Hartmann number field inclination average Nusselt are studied. results show that incr...

In this paper we give the main ideas to show that a real analytic vector field in R3 with a singular point at the origin is locally topologically equivalent to its principal part defined through Newton polyhedra under non-degeneracy conditions.

Feng and Zhu defined the permutation tree structure to achieve a running time of O(n logn) for Hartman and Shamir’s 1.5approximation algorithm for sorting genomes by transpositions. The present work describes the first available implementation of this algorithm using permutation trees. Our analysis of Hartman and Shamir’s algorithm also leads to a modified 1.5-approximation algorithm that achie...

Recent studies of the tunnelling through two opaque barriers claim that the transit time is independent of the barrier widths and of the separation distance between the barriers. We observe, in contrast, that if multiple reflections are allowed for correctly (infinite peaks) the transit time between the barriers appears exactly as expected. PACS. 03.65.Xp It is a well known result that the tunn...
