Thermal and hydraulic calculation in a model of industrial branched pipeline transporting a single-phase liquid flow

Abstract

This paper proposes a system of differential equations that describes changes of pressure and temperature of a stationary liquid flow through straight, turning, and branched pipeline sections. We developed a program, using the proposed system of equations, that carries through hydraulic and thermohydraulic calculations, allows to choose diameter of various pipeline systems. The key feature of the program is the ability to solve monophasic problems such as: friction losses; local resistance losses; heat dissipation into the environment; flow distribution.
