... of these solutions, which allows for space-dependent fluid density and velocity and time- and space-dependent temperature inside the tubing and the annulus. The analytical model is verified against the corresponding numerical model that solves the full mass, momentum, and energy conservation equations...

... if an important parameter affecting the working life of the string is neglected, such as tubing diameter. This paper presents an analysis of a new analytical model for predicting diameter growth, and compares the estimated working life of a tubing string when both fatigue and diameter growth are considered...
