Comsol化工过程模拟计算方法介绍

Comsol化工过程模拟计算方法介绍 Modeling in the chemical industry is traditionally done using one independent variable, examples being time for CSTR (Continuously Stirred Tank Reactor) or reactor length when modeling tubular reactors. Dealing with one variable in this way usually implies the solution of systems of ordinary differential equations that describe material and energy balances. It was not until recent years that modeling using more than one independent variable—such as time and space or several space variables—has become important. In large-scale production, small design changes brought about by simulation studies can lead to large savings in energy and material. In fine chemicals and pharmaceuticals, modeling and design using PDEs can lead to high, uniform product quality. This course provides an introduction to modeling with the Chemical Engineering Module, for solving the PDEs obtained in material and energy balances, and to the new Reaction Engineering Lab, which automatically defines these balances from reaction formulas. This printed material contains ready-made examples that guide you through the modeling procedure using those two packages. The exercises do not require any prior expertise in mathematical modeling to be rewarding. Enjoy your modeling! The COMSOL Team
