| Summary |
"Abstract (1) Methods of iterative solution for the partial-differential equations that govern the transient flow of gases in pipelines are obtained by using the method of characteristics and linear finite-difference techniques. Solutions are developed for 1) a constant gas compressibility factor throughout transient conditions, and 2) a variable gas compressibility factor at constant temperature dependent upon pressures encountered during transient flow. Theoretical studies are made to compare results using both approaches for pipelines operating at various constant flowing temperatures. Results show greater differences between the two methods at lower values of flowing temperature due to the more rapidly changing compressibility factor as a function of variable pressure. Abstract (2) Equations are developed for transient gas pipe flow using both a constant and variable gas compressibility factor. Solution is by characteristics method using linear finite-differences. Results are used to compare the effects of compressibility factor at various constant flowing temperatures"--Abstract, leaves ii-iii. |
