Abstract    We have simulated a magnetite nanoparticle based ferrofluid using Monte Carlo method. Two and three dimensional Monte Carlo simulations have been done using parallel computing technique. The aggregation and rearrangement of nanoparticles embedded in a liquid carrier have been studied in various particle volume fractions. Our simulation results are in complete agreement with the reported experimental observations. We have also checked the accuracy of our results with the predictions of theoretical expressions. In addition, we have applied the distributed computing method to reduce the run time of the program


Keywords    ferrofluid, Monte Carlo simulation, particle volume fraction, chain and cluster


چکیده    شبيه سازي نانوذرات مغناطيسي در سيالات مغناطيسي با استفاده از روش مونت كارلوانجام شده است. اين شبيه سازي در دو و سه بعد و با از روش محاسبات موازي استفاده شده است. تجمع و باز سازي نانو ذرات معلق در يك سيال حامل در نسبت هاي حجمي متفاوت مورد بررسي قرار گرفته است. نتايج شبيه سازي با گزارشات مشاهدات تجربي در توافق كامل است. همچنين درستي نتايج با استفاده از معادلا نظري امتحان شده است. به علاوه، براي كاهش دادن زمان اجراي برنامه، روش محاسبات توزيع شده مورد استفاده قرار گرفته است.
