Carbon monoxide is often produced during the incomplete combustion of volatile organic carbon compounds in industry. In chamber for oxidizing emissions, a penta-coaxial port device can be used to improve process mixing fuel and oxidizer. this study, conjugate heat transfer analysis was conducted by solving both Reynolds-averaged Navier–Stokes equations with eddy dissipation model solid conducti...

In this paper‎, ‎two extended three-term conjugate gradient methods based on the Liu-Storey ({tt LS})‎ ‎conjugate gradient method are presented to solve unconstrained optimization problems‎. ‎A remarkable property of the proposed methods is that the search direction always satisfies‎ ‎the sufficient descent condition independent of line search method‎, ‎based on eigenvalue analysis‎. ‎The globa...

a classical result of neumann characterizes the groups in which each subgroup has finitely many conjugates only as central-by-finite groups. if x is a class of groups, a group g is said to have x-conjugate classes of subgroups if g/coreg(ng(h)) 2 x for each subgroup h of g. here we study groups which have soluble minimax conjugate classes of subgroups, giving a description in terms of g/z(g). w...

In this paper we review main results of Raleigh Bénard convection. Keywords—Convection, Turbulence Thermal convection is present everywhere. We find it in heating sauce pans, boilers, furnaces, and in the atmospheres of planets and stars. Convection is one of the most studied problem in sciences and engineering due to its enormous practical importance. Yet there are many unresolved issues in th...

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...

[1] We investigate the physics of multiscale convection in Earth’s mantle, characterized by the coexistence of large-scale mantle circulation associated with plate tectonics and smallscale sublithospheric convection. In part 2 of our study, the temporal and spatial evolution of sublithospheric convection is studied using two-dimensional whole mantle convection models with temperatureand depth-d...

introduction: an effective vaccine against hcv infection is not available. the non-structural protein 3 (ns3) of the virus as an important immunogenic candidate has been utilized in various modules. nanostructured polymers have been recently used for efficient vaccine and drug delivery. the aim of the current study was the synthesis of rns3-g2 conjugate and preliminary evaluation of its immunog...

Large eddy simulations are performed to analyze the conjugate heat transfer of turbulent flow in a ribbed channel with heat-conducting solid wall. An immersed boundary method (IBM) is used determine effect region on that fluid unitary computational domain. To satisfy continuity flux at solid–fluid interface, effective conductivity introduced. By applying IBM, it possible fully couple convection...
