Design of Geometrical Dimensions of Betzs Ring Specimen Hypothesizs of Uniform Distribution of Electric Current

摘要: 列举了影响Betz环内真实电流分布的一系列不确定因素, 解释了目前难以对其精确建模的原因。根据电流充满导电体的特性, 采用了最简单的电流均匀分布假设来作为零级近似。由此假设的推论可得Betz环的几何尺寸间存在一定关系, 验算证明了Betz环的设计是合理的。

Abstract: A number of indeterminate factors influencing the true distribution of electric current flowing through the Betzs ring specimen were enumerated. The difficulty to model Betz ring at present was introduced. The simplest hypothesis, where the electric current uniformly distributes in the Betzs ring specimen as an approximation of zero degree, was postulated. It is deduced that the geometrical dimensions of the Betzs ring had to satisfy certain relationship. Checking computations indicated that the design of the Betzs ring specimen was rational.
