Forced air distribution systems can have a significant impact on the energy consumed in residences. It is common practice in U.S. residential buildings to place such duct systems outside the conditioned space. This results in the loss of energy by leakage and conduction to the surroundings. In order to estimate the magnitudes of these losses, 24 houses in the Sacramento, California, area were t...

In the paper a new method for computer aided modelling and identification of flow dynamics in molten glass is presented and numerically analysed. The process of the construction of the model occurs in several steps on which the sub-models with differentiated mathematical descriptions (with distributed or lumped differential equations) and dynamical features (with inertial and oscillatory charac...

Electric arc melting of oxide materials under the influence an external electromagnetic field is a high-current and high-temperature technological process, accompanied by powerful electric magnetic fields complex structural motion melt. In general case, movement melt in bath installation determined combination thermocapillary, thermal concentration, convections. this work, based on analysis con...

The paper describes the issues associated with waste generated during steel production and processing, in particular dust from electric arc furnaces (EAF). An effective solution for disposal of such is its involvement processing to obtain valuable products. This studies physical chemical properties EAF produced smelting metallized pellets captured by gas cleaning system steel-smelting shop at O...
