Through the research, design datas are provided for the enhancing product performance and competitiveness. In the paper, based on problems that exist in the construction of concrete mixing station, actual conditions of Tengzhou city and research results in China United cement plant, concrete mixing station’s overall structure is designed. And the structure’s harmonic response and dynamic proper...

Natural convection heat transfer from a tube bundle in the indirect water bath heaters is investigated. A computer-code is used for the solution of the governing equations of mass, momentum and energy transfer based on the SIMPLE-C algorithm. Simulations are carried out for the gas pressure station heater of Kermanshah city with various tube bundle arrangements. In order to validate the numeric...

This research aims to study the lead pollution in the air of Babylon governorate that resulted generally from vehicles exhausts in addition to industrial and human activities.Vehicles number in Babylon governorate increased significantly after year 2003 that resulted with increase in lead emissions into the air.Measurement of lead emissions was done in seven stations distributed randomly in Bab...

vegetation cover on a variety of different land uses in different parts of a city creates different forms of heat flow that this, in turn, generates the main framework of urban microclimate. the objective of this study is to survey the effect of land cover type on air temperature in the isfahan city. to do this, five regions in the isfahan city with different land cover type were selected. in e...

Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering heat from exhaust flue gas with a mixture of 40% water and 60% ethylene glycol as the coolin...
