چکیده

در این مقاله تولید ذرات ریزساختار نابومتن با استفاده از فرایند انبساط ناگهانی محلول های فوق بحرانی (RESS) مدل شده است. برای مدل سازی فرایند RESS از یک مدل ریاضی استفاده شده و با استفاده از این مدل، متوسط اندازه ذرات و توزیع اندازه ذرات نابومتن تخمین زده شده است. همچنین با استفاده از مدل ارائه شده، اثر شرایط عملیاتی موثر بر فرایند RESS از جمله فشار و دمای انبساط، فشار و دمای استخراج و فاصله اسپری بر روی مشخصات محصول تولید شده بررسی شده است. نتایج محاسبات نشان می دهند که تطابق خوبی میان نتایج تجربی و داده های محاسباتی وجود دارد.

چکیده [English]

A new model is proposed for production of fine particles of Nabutemon by rapid expansion of supercritical solutions (RESS). A mathematical model is used for prediction of particle size and particle size distribution of RESS produced particles. In this model the effect of various operating parameters such as pressure and temperature of extraction and temperature and pressure of expansion on the characteristics of products were studied. The calculation results showed good agreement between the calculation results and the experimental data for Nabutemon particles.
