the aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. thermal efficiency is defined as a function of unknown variables (fluid pressure and vapour ...

A scroll compressor has a bu~lt-in pressure ra~~o related to geometry of scroll wraps and efflciency of the compressor depends on the relation between the ratio and an operat~ng pressure rat~o. Th~s paper analyses theoretl.cal performance of the compressor by tak1ng account of flow resistances at opem.ngs of scroll wraps and leakage flows through wrap clearances. The flow resl.stance at the d1s...

A type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. The aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. The hypercross-linked fiber adsorbent possesses a principall...
