  The high potential of solar energy in Iran, as well as the problem of air pollution, makes it increasingly inevitable that solar energy is used. In this study, the solar-powered Organic Rankine cycle (ORC) has been investigated. The solar-type collector is a flat plate collector. The energy, exergy, ...  Read More

Volume 1, Issue 2 , Summer and Autumn 2020, , Pages 135-141


  Entropy generation can be caused by the energy transfer from a high-temperature recourse to a low-temperature resource; this is defined by the second law of thermodynamics. This phenomenon can occur for the Earth by transferring the solar energy from the sun to the earth. The process of entropy generation ...  Read More

Volume 1, Issue 1 , Winter and Spring 2020, , Pages 27-45


  Until 2026, the annual rate of municipal solid waste production will increase and the per capita waste generation in Iran will be 0.6 kg/person.day. In this paper, the process of conversion of waste-to-energy in Iran is investigated and the future situation is estimated. Also, the trend of waste management ...  Read More
