a numerical study has been done through an al2o3–water in a double lid-driven square cavity with various inclination angles and discrete heat sources. the top and right moving walls are at low temperature. half of the left and bottom walls are insulated and the temperatures of the other half are kept at high. a large number of simulations for a wide range of richardson number of ...
The air-gap of electrical machines may become non-uniform due to low accuracy of the manufacturing machinery, in assembling processes, or by aging. Detection and monitoring of this phenomenon is very important and of interest. There are several methods to model non-uniform air-gaps and to detect them by monitoring systems. One of the most widely used methods is by the analysis of the line curre...
به منظور بررسی و تحلیل رفتار سیال لزج در پروانه پمپ سانتریفوژ، حل عددی معادلات ناویر استوکس در محدوده بین دو پره متوالی انجام گرفته و توزیع فشار، سرعت و تنشهای دیواره با استفاده از مدل توربولانسی rng k- و rsm محاسبه گردیده است . ابتدا شبیه سازی جریان بریا پمپ دوبعدی صورت گرفته است و سپس برای حالت سه بعدی نیز این کار انجام شده است . برای انجام این کار از نرم افزار فلوئنت استفاده شد که نسخه موجود...
Non-uniform complexity measures originated in automata and formal languages theory are characterized in terms of well-known uniform complexity classes. The initial index of languages is introduced by means of several computational models. It is shown to be closely related to context-free cost, boolean circuits, straight line programs, and Turing machines with sparse oracles and time or space bo...
