in this paper, a new systematic design methodology has been developed for thes imultaneous energy and water minimization in multiple-contaminant systems that also feature maximum re-use of water. in addition to allowing re-use of water in multiple-contaminant systems, issues about heat losses and flowrate changes inside unit operations have also been incorporated in this new design method. to i...

In a cylindrical scraped heat exchanger crystallizer geometry the flow field influence on the local heat transfer distribution on an evenly cooled scraped heat exchanger surface has been studied by direct measurements of the heat exchanger surface temperature and the fluid velocity field inside the crystallizer. Liquid Crystal Thermometry revealed that the local heat transfer is higher in the m...

The thermal performance of a heat exchanger is important for the potential application in an integrated solar cell/module and thermoelectric generator (TEG) system. Usually, the thermal performance of a heat exchanger for TEGs is analysed by using 1D heat conduction theory which ignores the detailed phenomena associated with thermo-hydraulics. In this paper, thermal and momentum transports in t...

Abstract The development and application of enhanced geothermal system hydrothermal are constrained due to high cost risk induced seismicity or heavily reliance on hot water reservoir. Deep borehole heat exchanger (DBHE) technology is independent reservoir hydraulic fracturing; however, the poor thermal conductivity rocks limits its performance improvement. To deal with these problems, a novel ...

Increased concerns about climate change and day by day increment in energy cost has created the importance of Refrigeration & Air Conditioning system with high COP. COP of a Vapour Compression Refrigeration system is mainly influenced by the effectiveness of the Heat Exchanger being Employed. Optimization in the design of Heat Exchanger is highly desirable to improve their effectiveness and red...
