محاسبات تعادلات فازی برای پیشگویی تعادلات فازی و ترکیب در حال تعادل در عملیات و فرایند های مختلف شیمیایی نقش مهمی باز می کند. همان طور که می دانیم تعادلات فازی نیاز به کمیته سازی مطلق انرژی آزاد گبیس دارد و توابع ترمودینامیکی در این گونه مساله ها به شدت غیر خطی است لذا در این پروژه، از الگوریتم ژنتیک برای این هدف استفاده شده است. در این پروژه به تعادلات مایع-مایع، مایع-بخار، مایع-مایع-بخار و ما...
The extension of the translated–consistent Peng–Robinson (tc-PR) equation state (EoS) to mixtures has been investigated. For this purpose, advanced EoS/aresE,? mixing rules are used combine tc-PR EoS with residual part an activity coefficient model chosen among Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical (UNIQUAC) models. performances three resulting versions compared agai...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
The performance of three hydrophobic carboxylic acid based Deep Eutectic Solvents were evaluated for the extraction 1-butanol and acetonitrile from aqueous solution. To do so, phase diagrams five ternary systems {[DL-menthol: lauric acid] + water 1-butanol}, capric acetonitrile}, {[TBAMBr:capric 1-butanol} {[TBAMBr: measured at 298.15 K atmospheric pressure. Liquid-liquid equilibria data used t...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...
دادههای تجربی تعادلهای مایع- مایع، نمودارهای حلالیت ( بینودال) و خطوط رابط سیستمهای سهجزئی )آب + اسید پروپیونیک یا اسید بوتیریک + حلالهای آلی) در t = 298.2 k بدست آمد. حلالهای آلی این سیستمها، ایزوبوتیل استات و سیکلوهگزان می باشند. سیستم سه جزئی (آب + اسید بوتیریک + ایزوبوتیل استات) در t = (298.2, 303.2, 308.2) k بررسی شد.داده های تجربی خطوط رابط با مقادیر بدست آمده از مدلهای uniquacو nrtl م...
