... of a mathematical model to predict friction and heat transfer while pumping cement slurries and all the associated fluids through a coiled section. Based on momentum and energy conservation laws, the proposed model aims to generate representative transient pressure and temperature profiles to be coupled...

... Abstract The objectives of this research are: to analyze the effects of the catenary shape during the occurrence of severe slugging and to develop a simplified but accurate mathematical model to calculate the main parameters of severe slugging in a flowline - catenary riser system. Offshore...
