通过计算机模拟和实验测量，确定了二维电加热系统的温度分布。一个商业软件程序包用于模拟。该实验是在一个系统中进行的，其中的垂直尺寸是最小的，以尽量减少欧姆加热过程中的自然对流。在含有矩形颗粒的矩形静态系统中，计算机模拟显示了类似实验结果所验证的趋势。热损失的环境和模拟中使用的物理属性值的主要因素影响实验和模拟结果之间的差异。没有证据表明，除了粒子中心之外，还有任何最冷的点存在。
Temperature distribution in a two-dimensional electrical heated system was determined both by computer simulation and experimental measurement. A commercial software program package was used for simulation. The experiment was conducted in a system where the vertical dimension was minimal to minimize natural convection during ohmic heating. In a rectangular static system containing a rectangular particle, computer simulation showed a trend verified by similar experimental results. Heat loss to the environment and physical property values used in simulation were major factors affecting differences between experimental and simulation results. There was no evidence for the presence of any coldest spot other than at the center of particles.
