چکیده
The prediction of pressure gradients, liquid hold up and flow patterns occurring during the simultaneous flow of gas and liquid in pipes is necessary for designing well tubing and flow lines in the petroleum and chemical engineering. The flow may be vertical, inclined (upward or downward) and horizontal; and methods must be available for predicting pressure drop in pipes at any operational parameters including pipe and fluids properties. The engineer must be able to calculate liquid hold-up in the pipelines at various flow conditions in order to calculate such things as mixture density, actual gas and liquid viscosities, effective viscosity and heat transfer and as a result to design separation and slug catching facilities. The objective of this research is to develop a COMSOL mechanistic model for simulation of gas-liquid two-phase flow and use the experimentally validated model to provide thorough insight and understanding of the effect of different operational parameters such as inlet gas/liquid ratio, flow rate and flow inclination angle on the liquid hold up and pressure drop along the pipe. These multiphysics simulations can be used for understanding pertinent affecting parameters and designing real experiments.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
