the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

سیلاب ورودی به مخزن سد حاوی مواد معلق زیاد بوده که اصطلاحاً جریان چگال (density current) نامیده می شود. این جریان در واقع جریان یک سیال درون سیال دیگر است که بوسیله اختلاف چگالی مابین آنها ایجاد می گردد. اختلاف در چگالی که باعث ایجاد نیروی رانش می گردد ممکن است ناشی از اختلاف درجه حرارت، وجود ذرات معلق جامد ویا مواد محلول باشد. در این تحقیق با توجه به آزمایشات سه بعدی انجام شده، گسترش عرضی جریان...

This paper has examined the analytical solution of steady fully developed natural convective flow of a viscous incompressible and electrically conducting fluid between vertical channel by taking the Hall current and induced magnetic field into account. We have obtained the non-dimensional simultaneous ordinary differential equations using the suitable non-dimensional variables and parameters in...
