[ 1 ] - امکان‌سنجی به‌کارگیری روش گاما دنسیتومتری در اندازه‌گیری ضریب کسر حفرۀ جریان دوفازی در کانالی با مقطع مربعی
Precise measurement of void coefficient in two phase flow is one of important parameters in thermal hydraulic parameters such as average density, two phase flow pressure drop and two phase flow pattern. In this study the void coefficient has been correlated experimentally based on attenuation coefficient gamma ray emitted form 137Cs source passing a rectangular channel. The average void fractio...
[ 2 ] - بررسی رفتار الکترونیکی یک مدار دیودی در معرض تابش برای آشکارسازی پرتوهای گاما
The ionizing radiations are able to make either a permanent or temporarily damage in the electronic circuits. The temporary effects during irradiation can be used to detect the ionizing radiation. In this study a diode in reverse bias has been used to investigate the effects of ionization radiation on semiconductors. The variation of reverse current of diode has been monitored due to interactio...
[ 3 ] - تغییرات حرارتی-هیدرودینامیکی یک نانوسیال در یک لوله مجهز به نوار پیچشی: بررسی اثرات ساختاری نوار پیچشی
Thermal energy is one of the most important issues in most industries, because conversion of energy from fossil fuels to thermal energy occurs in almost all conventional industries. Therefore, considering the lack of fossil resources and the increasing pollution of human environments, attention to the proper use of thermal energy should be considered by researchers. In recent years, attention h...
