The purpose of the elbow with the installation

Wear-resistant elbow can be favored by the market and continue to replace some of the traditional wear-resistant materials, the root cause lies in its excellent product quality, as well as in the traditional wear-resistant materials and materials. In order to obtain the performance influence of the upstream elbow on the performance of the inner cone flowmeter and the length of the shortest straight pipe, the numerical simulation of the 90 mm diameter and equivalent diameter ratio 0.45/0.65/0.85 was carried out. Simulation medium is often warm water, Reynolds number range: 0.498 * 105 ~ 4.98 * 105, the research program is divided into two types of the baseline and the upper reaches of the single 90 degree elbow, a total of 15 groups. Based on the relative error of the average outflow coefficient and the main evaluation criteria of the installation condition, the length of a straight pipe with a single 90 degree elbow is presented and compared with the foreign research results.
