Abstract

The invention discloses an Apache Flink-based distributed fluid dynamics calculation method, which comprises the following steps of: data acquisition: receiving fluid data generated by a specific drainage basin, and collecting the fluid data acquired in real time in a distributed manner; data cleaning: using a map operator splitting function of an Flink platform to convert the collected fluid data one by one, using a flatmap operator splitting function of the Flink platform to convert each fluid data record from one line to multiple lines, using a keyby operator partitioning function of the Flink platform to perform data partitioning on each fluid data record according to a speed value field, and using a speed value field as a data partition; and putting the same speed value into the same partition. By using the flink framework, the data real-time processing is very strong, the data delay is not generated, the data consistency is ensured, and the data throughput is very strong, that is, the data can be frequently written into the flink and cannot be lost.

Description

technical field [0001] The invention relates to the technical field of fluid dynamics, in particular to a distributed fluid dynamics calculation method based on Apache Flink. Background technique [0002] With the rapid development of computer technology and large-scale parallel computing technology, computational fluid dynamics has become a commonly used fluid dynamics research method, and has a very wide range of applications in scientific research and engineering applications. However, the fluid flow phenomenon is very complex, and it is difficult to solve the governing equations of the fluid flow. The details of the fluid flow field are not enough to meet the relevant calculation requirements. The calculation efficiency is not high, the data processing is slow, and the data is easily lost. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a distributed fluid dynamics calculation meth...
