We explore how the inclusion of an anti-trapping current within a phase-field model of coupled thermo-solutal growth formulated in the thin interface limit actually affects the observed levels of solute trapping during dendritic growth. The problem is made computational tractable by the use of advanced numerical techniques including local mesh adaptivity, implicit temporal discreteization and a...

To study the material behavior of axisymmetric flow in micropolar fluid for heat and mass exchange over a stretchable disk placed porous medium taking into account effect generation, diffusion thermo, Brownian motion thermophoretic effect. A suitable similarity transformations is adapted to convert governing PDEs non-dimensional form. well-tested, numerically stable MATLAB code connection with ...

Hydrogels are widely studied for chemical sensors. However, they are known to adsorb organic compound and metal ions. The adsorption abilities of hydrogels against organic compounds and metal ions will negatively affect the performance of a hydrogel based chemical sensor. To clarify the effect of hydrophobic pollution on swelling behavior of temperature-sensitive gel, the temperature-responses ...

Abstract The progress of mean-field modeling and simulation in steel is presented. In the modeling, focus put on development application a physical base, including Calphad, diffusion assessment, nucleation growth precipitates, dislocation dynamics. This leads to an improved prediction materials response after different thermo-mechanical treatments terms microstructure evolution mechanical prope...

Rubber-like materials can undergo very large strains in a quasi-reversible way. This remarkable behavior is often called hyper (or entropic) elasticity. However, the presence of mechanical loops during a load-unload cycle is not consistent with a purely elastic behavior modeling. Using Digital Image Correlation and Infra-Red Thermography, the present study aims at observing and quantifying diss...

In the present research, to form niobium carbide coating on the surface of AISI L2 steel Thermo-Reactive Deposition method (TRD) in a molten bath was used. Niobium carbide coating treatment was carried out at 1173 K, 1273 K, and 1373 K for 2, 4, and 8 hours. The molten bath contained 20wt.% borax (Na2B4O7), 5 wt.% boric acid (B2O3), and 75 wt.% ferro-niobium. The presence and properties of...

i. Thermo-physiological comfort: achieving a comfortable thermal and humid condition in which the thermo-regulating capacity, the thermal insulation and the moisture-regulating capacity of the garment are considered as a function of environmental conditions (climate) and the working conditions (level of effort). Thermo-physiological comfort is strongly affected by the fabric, the style and the ...
