Cure kinetics of a polysilazane system: Experimental characterization and numerical modelling

Tungsten Carbide Fragmentation: Experimental Characterization and Numerical Modelling

Tungsten Carbide is a high density ceramic (generally found in ceramic/metal mixtures) with attractive shear and tensile strength properties in certain ballistic applications. We have determined a Hugoniot elastic limit of ~4 GPa, followed by strong hardening behavior, with spall strengths of 2.7-3.6 GPa. In addition, a series of experiments where Tungsten Carbide spheres impacted PMMA indicate...

Modelling and Experimental Study of Wax Deposition in Transportation Line Using a Flow Loop System

Numerical Modelling of Porous Radiant Burners Using Full and Reduced Kinetics Mechanisms

The present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (PRB), with their reduced forms. The two most frequently used mechanisms of methane combustion (GRI3.0 and Miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. While the findings of numerical simulation of PRB sho...

experimental and numerical modelling of flow pattern on

abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...

Cure Kinetics and Rheology Characterization of Soy-based Epoxy Resin System

A novel soy-based epoxy resin system was synthesized by the process of transesterification and epoxidation of regular soy bean oil, which has the potential to be widely usable in various composite manufacturing processes. Cure kinetics and rheology are two chemical properties commonly required in process modeling. In this work, the cure kinetics and rheology of the soy-based resin system were m...
