... Abstract Air-water two-phase flow in circular pipes has been studied by many investigators. Because of the important effect of flow patterns on the flow and heat transfer, investigations on flow patterns are still very active. On the other hand, investigations of flow patterns in noncircular...

... these technologies are heating or dilution of the heavy oil and sometimes a mixture of both of these methods. The majority of oil storage terminals contain pipes that are installed above ground and in northern countries are prone to experiencing cold temperatures during winter months. In part of the terminal where...

... ABSTRACT This paper defines and studies a simple, efficient method for discretizing pipeline equations in time. In many ways the solutions of pipe flow equations look like the solutions of nonlinear diffusion equations, so it is natural that schemes that work well for diffusion problems might...

... ABSTRACT An important variable considered in the sizing and design of pipelines is the absolute roughness of the pipe, which is used to calculate the pressure loss during fluid flow through the pipeline. The default value for absolute roughness of commercial steel pipe, as generally used...

... the pipeline damage is close to a gate station with SCADA recording, it is possible to obtain an hourly flow profile at the break. Second, simple configurations of pipe rupture have been replicated in laboratory and tested with air. For most of the cases, the described methodology shows a good match...

... conditions must be known in order to have a defined calibration solution. Pipes that run parallel to each other (i.e. from the same upstream location to the same downstream location in roughly the same right-of-way) can pose serious difficulties to this requirement, especially when no inline flow measurement...

... of them when they aren't, and maintain a guarantee that the model solution is accurate to some user-specified level. Adaptive meshes are widely used in fields such as reservoir simulation[1] and pipe stress simulation[2], where 2D and 3D partial differential equations (PDEs) are solved, but haven't found...

... Abstract This article deals with the gas reservoir and the blow-off pipe as a unit. Implicit relations for sonic and subsonic outflows through pipes of any length are presented. Explicit approximate relations are provided as well. The formulas have been applied to determine valve influence...

The advantages of such a decoupling are reduced complexity and improved computational speed. But what is the cost? Is the accuracy...

... ABSTRACT While single-phase pipe flow is almost always assumed to be one-dimensional, that is, homogeneous across the pipe's diameter, there can potentially be two-dimensional thermal effects in the laminar flow of high-viscosity oil. The heat that's initially imparted to the oil by heaters...
