Compressible Fluid Flow Calculation Methods

A generalized comparison of three pressure-drop calculation methods is developed, guiding engineers in making the proper assumptions when evaluating compressible fluid flow

Fucheng Teng, Pedro Medina and Mark Heigold Jacobs Canada, Inc.

When considering the flow of compressible fluids, which have significant variation in density along pipelines, three special flow conditions are often examined, in order to simplify calculations: incompressible (fluid density is constant), isothermal (fluid temperature is constant) and adiabatic (there is no heat transfer between the fluid and its surroundings). Through thorough derivations and analysis of literature, this article will delve deeper into these calculation methods to form a valid comparison....
