A computer program was developed to compute the profile of multiple-beam Fizeau fringes and was tested against laboratory observations. By using the program as a tool for studying the behavior of the fringes, a simplified model of the fringe formation process was developed. The shifts of the fringes from their expected locations are caused primarily by a reduction in spatial frequency that is d...

In this study, an adaptive neuro-fuzzy inference system (ANFIS) was developed to determine the Nusselt number (Nu) along a wavy wall in a lid-driven cavity under mixed convection regime. Firstly, the main data set of input/output vectors for training, checking and testing of the ANFIS was prepared based on the numerical results of the lattice Boltzmann method (LBM). Then, the ANFIS was develope...

The buoyancy-driven fluid flow and heat transfer in a square cavity with partially active side walls filled with Cu-water nanofluid is investigated numerically. The active parts of the left and the right side-walls of the cavity are maintained at temperatures Th and Tc, respectively, with Th>Tc. The enclosure’s top and bottom walls, as well as, the inactive parts of its side walls are kept insu...

The two-dimensional, time-independent conjugate natural convection flow and entropy generation are numerically investigated in three different cases of a wavy conducting solid block attached to the left wall square cavity. A hybrid nanofluid with titania (TiO2) copper (Cu) nanoparticles base fluid water part is considered presence uniform inclined magnetic field. leftmost cavity hot one rightmo...

In this paper, we present a numerical study of turbulent natural-convection in square cavity differentially heated and filled with nanofluid subjected to an inclined magnetic field. The standard k-? model was used as the turbulence model. transport equations were discretized by finite volume method using SIMPLE algorithm. influence Rayleigh number, Hartmann orientation angle applied field, type...

this paper is a computational study of the behavior of aerodynamics  characteristics of an airfoil with blunt trailing edge and  studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...

Numerical findings of natural convection flows in a trapezoidal cavity are reported this study. This study focuses on the shift from symmetric steady to chaotic flow within cavity. has heated bottom wall, cooled top and adiabatic inclined sidewalls. The unsteady occurring numerically simulated using finite volume (FV) method. fluid used is air, calculations performed for different dimensionless...

The proto-oncogene, BCL-2, has been suggested to participate in cell survival during development of, and after injury to, the CNS. Transgenic (TG) mice overexpressing human Bcl-2 (n = 21) and their wild-type (WT) littermates (n = 18) were subjected to lateral controlled cortical impact brain injury. Lateral controlled cortical impact brain injury resulted in the formation of a contusion in the ...
