TRANSIENT SIMULATION OF TWO-PHASE FLOWS IN PIPESTransient simulation of two-phase gas-liquid flow in pipes requires considerable computational efforts. Until recently, most available commercial codes are based on two-fluid models which include one momentum conservation equation for each phase. However, in normal pipe flow, especially in oil and gas transport, the transient response of the system proves to be relatively slow. Thus, it is reasonable to think that simpler forms of the transport equations might suffice to represent transient phenomena. Furthermore, these types of models may be solved using less time-consuming numerical algorithms.
SIMULACIîN TRANSITORIA DE LOS FLUJOS DIFçSICOS EN LOS CONDUCTOS.La simulaci-n transitoria de los flujos dif ‡sicos de gas l'quido en los conductos, precisa esfuerzos de c ‡lculo considerables. Hasta hace poco tiempo, la mayor parte de los c-digos de simulaci-n comercialmente disponibles se fundaban en modelos de dos fluidos que aplican una ecuaci-n de conservaci-n de la cantidad de movimiento para cada fase. No obstante, en los procesos normales de transporte de hidrocarburos por medio de conductos, y especialmente al tratarse del transporte de petr-leo y de gas, la respuesta transitoria del sistema se manifiesta ser de forma relativamente lenta. Por todo ello, parece razonable pensar que una forma simplificada de las ecuaciones de transporte, podr'a ser de forma suficiente para la reproducci-n de tales fen-menos transitorios. Adem ‡s, este tipo de modelo se podr'a resolver por v'a digital mediante algoritmos menos costosos en cuanto a tiempos de c ‡lculo.
