دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
In recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. Researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. Moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...
Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...
in this research, industrial wastewater treatment plants (iwwtps) were investigated and categorized by effluent applications and electrical energy cost. for the purpose of this research, 51 plants were assessed and results indicate that 17 plants discharged the effluent directly to the surface water that most of them are located in north of iran, 24 plants used the effluent for irrigation. othe...
In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...
Cost of cement producing all over the world depends on to the level of wages, energy cost and availability of raw materials. By investigating financial statements of various companies at the stock market, the share of electrical and fuel costs are nearly 27 percent of total costs and this plays the important role in right management of energy consumption. In this regard mathematics modeling and...
By undertaking a cointegration analysis with annual data over the period 1985~2005 in China, the estimation results show that there is cointegration relationship between electrical energy consumption and economic growth taking into account industry structure changes and technical efficiency. The model shows that three explanatory variables, the GDP per capita, heavy industry share and efficienc...
steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...
pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...
open local energy requirements, the need for regional energy planning in the process of macro-planning can make significant energy. in this respect, the outer part of the direct effects of energy production and consumption locally effective, less energy planning processes will be huge. in this paper, the issue of continuity of energy supply, long-term access to resources and lower emissions fro...
