THERMAL AND INERTIAL CORRECTIONS FOR THE HOLE PRESSURE PROBLEM
The hole pressure problem is an area of active research in non-Newtonian fluid mechanics. the objective being to relate hole pressure measurements to a property of polymeric liquids known as the first normal stress difference. The present work focuses on the Higashitani-Pritchard theory (HP theory). which is successfully ...
Dielectric thermal analysis of polymeric matrices
While the commercial application of polymeric composite materials is increasing, methods of processing composites are becoming more complex and cost prohibitive. Several in situ monitoring techniques have been proposed to permit the development of "smart" processes, which would reduce processing time and cost per part. One ...
Numerical Modeling With A Moving Coordinate System; Application To Flow Through Porous Media
A new numerical technique for solving convective diffusive equations is developed. Convective diffusive equations arise from mass conservation relations in flow through porous media. When convection dominates diffusion the equations are very difficult to solve numerically, because inaccurate oscillating solutions can result. ...
A Theoretical Model of the Kraft Pulping Process
A theoretical model of a batch kraft pulp digester is developed that predicts, ~ priori, the lignin content distribution, the carbohydrate content distribution, and the effective alkali concentration distribution within pulp chips as a function of cooking time. From this information the kappa number, yield, screen rejects, ...
Controlled release technology: development of a slow release systemic repellent for the protection of tree seedlings from deer
Modern forestry practices now include the use of many controlled release products, such as herbicides, pesticides fertilizers, superabsorbents, growth stimulants and animal repellents. Optimal use of these devices requires models that predict desirable release kinetics. Although some progress has been made in the development ...
