the use of solar collectors in combination with heat pipes is rapidly growing in recent years.heat pipes, as heat transfer components, have undeniable advantages in comparison with other alternatives. the most important advantage is their high rate of heat transfer at minor temperature differences. although there have been numerous studies on the heat analysis or first thermodynamic analysis of...

The experience of developed countries shows that the development road network and transport infrastructure determines intensity economic ties is one most important conditions for state’s economy. Optimization composition production technology asphalt concrete mixture – basis paved roads, great importance, both from an environmental point view. directly (during process at plants) indirectly deli...

The mathematical model to predict the performance and the exergetic efficiency in a multi-effect desalination system with thermal vapor compression (MED-TVC system) has been presented. The energy and the concentration conservation law were developed for each effect, considering the boiling point elevation and the various thermodynamic losses by developing the mathematical models. These analyses...
