基于电流均匀分布假设的Betz环几何尺寸设计

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

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。

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.
