“…Also, this model indicates that, the frictional pressure loss could theoretically be the same even at three different flow rates. In this case, this kind of an unstable flow characteristic should have two extremes and the flow rate of the system corresponding to that can be determined from equation below d∆P dQ = 3AQ 2 + 2BQ + C = 0 (8) Obviously, having the presence of a stable characteristic, Eq. (8) should not have real roots, which is possible if B 2 < 3AC has been determined from Eq.…”

“…Predicting reservoir and pipe or flowlines performance and economy requires accurate modelling of the hydrodynamics of this process [2,4,11]. Mathematical modelling is commonly used for resolving this flow characteristics and associated issues [8,28,29]. However, it is quite complex process and difficult to develop a reliable model for predicting the occurrences correctly [19,30].…”

The conventional equations for describing the flow characteristics of the mixtures merely consider fluid that is homogenic, if it is above the bubble point conditions but ignore that a system containing sub-micron sized gas or vapor bubbles distributed throughout the volume of the liquid, which can exhibit unexpected heterogenic and complex phase properties. In this paper, a new mathematical model for the flowing gas-liquid mixture is presented, which has been proposed considering the colloidal feature of the system above the saturation or bubble point pressure. This approach is more in line with the actual dynamic performance of the oil and gas mixture export pipeline. Experimental data, simulations and field case studies validate the new proposed mathematical model of flow characteristics in pipeline. The obtained results confirmed that the calculated data are in good agreement with the experimental data. Based on Azerbaijan oil-gas-condensate field “Guneshli” data, this new model was used for calculating the condition in which the transformation of the flow characteristics from stable into instable is occurred. It has been discovered that the flow becomes unstable at a pressure about 30% higher than Bubble Point Pressure, which causes pulsation effect in the pipeline structure. However, homogenic behavior should be observed in this hydrodynamic condition. Also, the model provides a guideline on how to optimize the flow rate by adjusting the pipeline parameters to minimize the flow resistance, liquid slugging and hydraulic hammering effects, which cause instable operation.

“…This separation may be due to the interactions of inertia of water and the buoyancy of the gas (Duan et al, 2015;Chisholm, 1980). As such, in the upward part of the pipe, only partial of gas CO 2 can flow upwards and towards further (or inject) into the sediments, as shown in Fig.…”

“…The fluid flow in geothermal pipes is turbulent and different models can be used to model the turbulence. Duan et al [9] carried out a numerical analysis of a two phase stratified smooth turbulent flow through a circular pipe. They studied a steady, two-dimensional momentum equation and employed a low Reynolds turbulence model.…”

In this study, two-phase non-Newtonian turbulent fluid flow in an inclined geothermal pipe with chemical reaction was considered. The governing nonlinear partial differential equations derived were solved numerically using Finite Difference Method. Influence of flow parameters on the temperature, concentration and velocity profiles were analyzed graphically. From the mathematical analysis of the model, it was established that the chemical reaction parameter significantly influenced the concentration distribution in both gaseous and liquid phases. Findings further revealed that decreasing the chemical reaction parameter resulted in decreased concentration of the geothermal fluid, which causes corrosion of geothermal pipes. These findings provide important information to engineers and researchers in making better decisions in terms of design, sizing and maintenance of flow systems in geothermal pipes.
