The objective of this work is to predict the temperature of the different types of walls which are Ferro cement wall, reinforced cement concrete (RCC) wall and two types of cavity walls (combined RCC with Ferrocement and combined two Ferro cement walls) with the help of mathematical modeling. The property of low thermal transmission of small air gap between the constituents of combine materials...

Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of green house gases, such as CO2, to the atmosphere. Among the greenhouse gases,CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmospher...

A Response surface design of experiment has been performed based on the Muschelknautz method of modeling (MM) for 64 test cases using Box-Behnken design to study the effect of seven geometrical cyclone dimensions on the pressure drop and cut-off diameter. It is found that the most significant geometrical parameters are, the vortex finder diameter, the inlet section width and height, and the cyc...

the objective of this study was to simulate carbon monoxide (co) dispersion exited from the stacks of a cement industry in doroud, iran by gaussian model (gm). four sampling period was conducted for the measurement of co from the factory's three-stack flow during a period of one year. the input parameters were the rate of co emission, meteorological data,  factors related to the stack, and...
