Joule-Thomson 효과를 고려한 천연가스 배관내의 온도 변화

Temperature Variations in the Natural Gas Pipeline with the Joule-Thomson Effect

A numerical method for determining the temperature vartiation in a natural gas transmission line is presented. By considering an element of the gas pipeline and assuming radially lumped heat transfer at steady-state conditions, the energy equation is developed. The integration of the developed nonlinear differential equation is done numerically using the fourth order Runge-Kutta scheme. The results of the present study have been compared with the results of Coulter equations, and show a fairly good agreement.
