[ 1 ] - نقش دو گونة گیاهیRumex Pulcher و Verbascum Songaricum در جذب برخی عناصر سنگین در مناطق اطراف معدن مس سرچشمه
معدن مس سرچشمه در جنوب غرب کرمان یکی از معادن روباز بزرگ جهان و یکی از قطب های مهم معدنی و صنعتی کشور است. خاک این منطقه به طور طبیعی و همچنین دراثر فعالیتهای معدنی حاوی فلزات سنگین است. درحال حاضر روش?های متنوعی برای کاهش آلودگی خاک به کارمی رود. بیشتر این روش?ها زمان بر و پر هزینه اند. استفاده از گیاهان مناسب برای آلایش زدایی خاک های آلوده به این فلزات به علت قیمت پایین و کم کردن تخریب های ز...
[ 2 ] - Vibration of Road Vehicles with Non linear Suspensions
In order to investigate the effects of non-linear springs in vibrating behavior of vehicles, the independent suspension of conventional vehicles could be modeled as a non-linear single degree of freedom system. The equation of motion for the system would be a non-linear third order ordinary differential equation, when considering the elasticity of rubber bushings in joints of shock absorber. It...
[ 3 ] - Vibration Analysis of Beams Traversed by a Moving Mass
A detailed investigation into the analysis of beams with different boundary conditions. carrying either a moving mass or force is performed. Analytical and numerical techniques for determination of the dynamic behavior of beams due to a concentrated travelling force or mass are presented. The transformation of the familiar Euler-Bernoulli thin beam equation into a series of ordinary differentia...
[ 4 ] - Computer Simulation of Ammonia Cold Shot Converter
A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...
[ 5 ] - Experimental Investigation into the Hydrodynamics Effects of Slot Film Cooling on a Cylindrical Model
An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...
