manufacturing new hepatitis b virus vaccines, specifically by the use of nanoparticles, is of high global interest. in this paper, a new biocompatible and biodegradable structure of nano-sized hepatitis b virus’ surface antigen (hbsag) was generated by conjugation with dendrimers, a low cost biodegradable and biocompatible polymer. the physicochemical properties of the conjugate were characteri...

Li-ion battery packs provide high energy density but with a concern of thermal management. Hence cooling mechanism is necessary to have good life and reliability on the system. The main objective this article investigate effect conjugate non-conjugate boundary conditions pack heat transfer characteristics. In conditions, coolant flow considered flux continuity at fluid interface. condition, jus...

Modern technologies of thermal power engineering make it possible to design and build systems using renewable energy sources. Often, accumulation storage require the development adaptation appropriate systems, simplest which are passive based on phase-change materials. In this study, a numerical analysis heat transfer in brick wall containing several materials with different melting temperature...

The aim of the present numerical study is to analyze the conjugate natural convection heat transfer in a differentially heated square enclosure containing a conductive polygon object. The left wall is heated and the right wall is cooled, while the horizontal walls are kept adiabatic. The COMSOL Multiphysics software is applied to solve the dimensionless governing equations. The governing parame...

We consider a system coupling the incompressible Navier–Stokes equations to the Vlasov– Fokker–Planck equation. Such a problem arises in the description of particulate flows. We design a numerical scheme to simulate the behavior of the system. This scheme is asymptotic-preserving, thus efficient in both the kinetic and hydrodynamic regimes. It has a numerical stability condition controlled by t...

The braking system of a racing car is one the main design challenges. flow around and inside wheel an F1 with all components analyzed in order to evaluate heat transfer after event. Very few studies have been published on this topic, mainly due high confidentiality level sector. In present work, using actual geometry early 2000s car, simulated CFD approach. boundary conditions for brake are tak...

In this paper a numerical study of two-dimensional conjugate natural convection in square cavity containing heated cylinders and outer isothermal boundaries is performed. The cavity is designed to simulate an unfilled trough containing electrical cables. The purpose of this paper is to investigate the effect of geometrical arrangements of electrical cables in underground cable ducts on the heat...

[1] Using ultraviolet images from two global auroral imagers, IMAGE FUV in the northern hemisphere and Polar UVI in the south, we present the first synoptic scale conjugate observations of the dayside aurora. We find that the morphology of the afternoon aurora is significantly different in the two hemispheres. Multiple spots in a ‘‘string of pearls’’ configuration are seen in the southern hemis...
