Abstract AR
يهتم هذا البحث بدراسة تأثير درجة الحرارة على الخواص الريولوجية (نقطة الخضوع، اللزوجة اللدائنية و اللزوجة الظاهرية) للمستحلبات.
تم تحضير 27 نموذج مستحلب، حيث كل المستحلبات المحضرة هي مستحلبات عكسية عندها تكون قطرات الماء منتشرة خلال زيت الديزل و النتيجة تسمى مستحلبات ماء-في- نفط.
تم دراسة الخواص الريولوجية لهذه المستحلبات باستخدام جهاز (Fann- VG-35A) و ذلك بقياس إجهاد القص (Shear stress) المصاحب لكل معدل قص (Shear rate) و باستخدام ثلاث درجات حرارية مختلفة (167، 122، 67) فهرنهايت.
تم استخدام برنامج مايكروسوفت إكسيل لإيجاد أفضل نموذج رياضي يمثل النتائج العملية و قد وجد إن نموذج بنكهام اللدائني هو الأفضل.
Abstract EN
This research deals with the study of the effect of temperature on the rheological properties (yield point, plastic viscosity and apparent viscosity) of invert emulsions.
Twenty seven emulsion samples were prepared ; all emulsions in this investigation are invert emulsions when water droplets are dispersed in diesel oil, the resulting emulsion is called water-in-oil emulsion (W / O).
The rheological properties of these emulsions were investigated using a couett coaxial cylinder rotational viscometer (Fann-VG model 35 A), by measuring shear stress versus shear rate at different three temperatures (77, 122, and 167) F°.
By using the Solver Add in Microsoft Excel®, the Bingham plastic model was found to be the best fits the experimental results.
It was found that when temperature increased, it causes a decrease in the rheological properties (yield point, plastic viscosity and apparent viscosity) of emulsions which is due to the change in the viscosity of continuous phase of emulsion that is diesel oil.
