Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling system including counter current helically coiled tube in tube heat exchanger, expansion valve...

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...

A case study of the manufacture an OTEC factory on a floating ship has been carried out using 100 MW Titanium material at fairly expensive cost, so system was researched copper-tin alloy. The behavior tin-copper heat exchanger between Aspen Plus simulation and Computational Fluid Dynamics (CFD) Shell And Tube evaporators Bonnet Divided Flow fixed One-pass (BEM) types is investigated. difference...
