The finite solid–liquid interface width in phase field models results non-equilibrium effects, including solute trapping. Prior modeling has shown that this extra degree of freedom, when compared to sharp-interface models, trapping is well captured realistic parameters, such as width, are employed. However, increasing the which desirable for computational reasons, leads artificially enhanced th...
Digital holographic microscopy (DHM) is an emerging high-resolution imaging technique that offers real-time imaging and quantitative measurements of physiological parameters without any staining or labeling of cells. The first DHM images of living cells were obtained 8-10 years ago [1, 2]. Analysis of human hepatocytes showed that DHM was a versatile tool for in vivo cell analysis by using quan...
in order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. the test rig has longitudinal trapezoidal slots in its conveying pipes. through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and froude number is presented. it is shown that the mixture friction factor for pipes with inner t...
In this study it was tried to investigate on the effective parameters of the formation and increasing tetragonal zirconia phase in reaction sintering of alumina and zircon. In this way, alumina and zircon powders were mixed by the ratio of 85 to 15 wt.% and sintered at different conditions. Sintering temperature (1500-1650˚C), furnace type (conventional and microwave) and the milling time of r...
In this paper, the effect of MgCl2 addition on the kinetics of MA spinel formation was investigated. For this purpose, the stoichiometric mixture of MgCO3 and calcined aluminum was calcined at 1100 °C for 1 hr. Then, the calcined composition was wet-milled and after addition of 6% MgCl2 the compositions were pressed and fired at 1300 and 1500 °C for different times. Spinel phase content was de...
