Resin Transfer Molding (RTM) is a composite manufacturing process. A preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. In this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. A numerical simulation is presented to predict the free surface and its inter...

In the current work, flow characteristics of single isothermal and non-isothermal jets discharging into upper plenum a 1/16th scaled-down high-temperature gas-cooled reactor (HTGR) facility were studied. ANSYS Fluent simulations carried out in central plane jet water for different Reynolds numbers (Re) ranging from 3413 to 12,819. Then, statistical characteristics, such as mean velocity, root-m...

We derive a model for the non-isothermal reaction-diffusion equation. Combining ideas from non-equilibrium thermodynamics with energetic variational approach we obtain general system modeling evolution of chemical reaction mass kinetics. From this recover linearized close to equilibrium and analyze global-in-time well-posedness small initial data critical Besov space.

A quantitative multi-phase-field model for non-isothermal and polycrystalline solidification was developed applied to dilute multicomponent alloys with hexagonal close-packed structures. The effects of Lewis coefficient undercooling on dendrite growth were investigated systematically. Results show that large coefficients facilitate the release latent heat, which can accelerate while suppress ti...

In energy geostructures, the soil-structure interface is subjected to thermo-mechanical loads. this study, a non-isothermal model based on critical state theory developed from granular constitutive under isothermal conditions. The capable of capturing effect temperature sand/clay-structure interfaces constant normal load and stiffness First, was verified for sand-structure in Then, it calibrate...

Injection and distribution of argon in a ladle shroud-collector plate nozzle (LS-CN) assembly have been investigated for three different gas delivery designs popularly used the industry to these ends, physical mathematical modeling has carried out. It is shown that flow around isolated perfect LS-CN can be effectively studied through water modeling, by introducing water, lieu argon, correspondi...

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...
