in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

Abstract: The present study deals the theoretical modeling aspects of coupled conductive and radiative heat transfer in the presence of absorbing, emitting and scattering gray medium within two-dimensional square furnace including two flames. The gray radiative medium is bounded by isothermal walls which are considered to be opaque, diffuse and gray. The well known discrete ordinate method (DOM...

The morphology of tectoreticular neurons in turtles was examined with serial section reconstructions of neurons retrogradely filled with HRP. Six classes of tectal neurons project into the three tectobulbar pathways characterized in the preceding paper (Sereno. '85). (1) Large multipolar neurons with somata in the central gray layers, and with moderately branched dendrites sometimes spanning ov...

| A procedure for estimating the joint probability density function (pdf) of T 1 , T 2 , and proton spin density (P D) for gray matter (GM), white matter (WM), and cerebrospinal uid (CSF) in the brain is presented. The pdf's have numerous applications, including the study of tissue parameter variability in pathology and across populations. The procedure requires a multispectral, spin echo magne...

The inheritance of rind pattern and color in watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) has been studied since the 1930s. The most common rind (or skin) colors in watermelon are solid green (dark, medium, and light), striped (narrow, medium, and wide dark green stripes on a light green background), and gray (a light green background with a medium or dark green network of reticulati...

The paper addresses the effects of Soret on unsteady free convection flow of a viscous incompressible fluid through a porous medium with high porosity bounded by a vertical infinite moving plate under the influence of thermal radiation, chemical reaction, and heat source. The fluid is considered to be gray, absorbing, and emitting but non-scattering medium, and Rosseland approximation is consid...

According to the granulometric composition of all soil types (typical, light gray, gray-meadow and meadow-alluvial) located on terraces I - II III Zarafshan oasis, it is mainly medium heavy sand, physical clay (<0.01 mm) large dust (0.05 – 0.01 mm), (0.01 0.005 fine (0.005 0.001 silt particles due irrigation for many years reduced sand increased amount in layers . It explained by erosion fel...

Application of the discrete transfer method is extended to solve transient radiative transport problems with participating medium. A one-dimensional gray planar absorbing and anisotropically scattering medium is considered. Both boundaries of the medium are black. The incident boundary of the medium is subjected to pulse-laser irradiation, while the other boundary is cold. For radiative paramet...
