A Java-based Program for Numerical Computation of Hydraulic Shock

摘要

Numerical solving, by method of characteristics, of the hydraulic shock problem required to develop a computer program that automatically respond to the following requirements: easy management of several projects, easy introduction, editing and change of data entry, and proper display of the program output: the hydraulic load and speed for every moment of time. The program is written in Java programming language. The calculation was done to study the phenomenon of hydraulic shock in the following schedule: pump -pipeline - tank (PCR) without changing the section of heading pipeline; tank - pipe - valve (RCV) for a section of the pipeline; tank - pipe - valve (RCV Complex) with changing cross-section of pipeline. The output refers to the values of speeds and hydraulic loads of the sections along the pipeline, elements that can assess system behavior in a given situation.
