Modeling of Heavy-Oil Flow with Regard to Their Rheological Properties

چکیده
With the depletion of traditional energy resources, share heavy-oil production has been increasing recently. According to some estimates, their reserves account for 80% world’s oil resources. Costs extraction heavy and natural bitumen are 3–4 times higher than costs extracting light oil, which is due not only density viscosity indicators but also insufficient development equipment technologies extraction, transportation, processing such oils. Currently, a single pipeline system used pump both oil. Therefore, it necessary take into features pumping mode. This paper presents mathematical models flow in oil-field pipelines. The rheological properties several samples were determined by experiments. dependencies obtained as input data simulation model using computational fluid dynamics (CFD) methods. modeling condition investigates range shear rates up 300 s?1. At same time, results 30 s?1 considered developed models. methodology research is, thus, based on CFD approach with experimental confirmation obtained. proposed reflects internal structural transformation during petroleum transportation. validity confirmed comparison between theoretical results. conducted can be selection treatment techniques its efficient

Modeling the Time-Dependent Rheological Properties of Pistachio Butter
Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...
متن کاملRheological, Physical and Sensory Properties of Mayonnaise Formulated with Sesame Oil
Fat has an important role in creating texture, color and viscosity; but, it might be a source of many diseases in human. Mayonnaise is one of the most widely used sauces that contains fat in its formulation. There is an increase demand in reduction of the amount of fat in the diet or use of unsaturated fat. In the present study, mayonnaise samples containing various amounts of sesame oil were p...

15 صفحه اولModeling the Rheological Properties of Carboxymethylcellulose Stabilized O/W Emulsions Based on Sunflower Oil and Tallow Fat
The aim of this research was to assess the effect of fat type and concentration as well as the continuous phase viscosity on the rheological properties of an oil-in-water (O/W) emulsion. Thus, sunflower oil and tallow fat were used as the dispersed phase of the emulsion both at 10 and 50% (w/v) and CMC solutions (at 0.1, 0.3 and 0.5% w/v) were acted as the continuous phase. CMC solutions and em...
