Proses perpindahan kalor pada dunia industri saat ini, merupakan proses kunci kerja dalam suatu mesin, karena semua mesin bekerja temperatur yang cukup tinggi. Salah satu alat penukar (Heat Exchanger), digunakan untuk menukar antara fluida memiliki perbedaan temperatur. Oleh itulah penggunaan heat exchanger perlu diperhatikan performanya secara teratur dengan performa buruk dapat berakibat kega...

Shell and tube heat exchangers are one of the most used exchanger types in applications it is important to predict transfer capacity pressure loss both design stage. Heat a can be enhanced by using tubes having surfaces instead smooth ones. In this study, usage corrugated shell investigated ε-NTU method, energy/exergy analysis. The impact on hot cold fluid outlet temperatures, efficiencies, ent...

The objective of this paper is to study the effect nanofluid on performance heat exchanger, as well transfer rate, coefficient total transfer, friction influence and average Nusselt number, thermal efficiency factor has been investigated discussed. In work, output Fe3O4/water through shell tube exchanger numerically under laminar flow. CFD simulations with ANSYS FLUENT 2020R1 were used adopting...

The S30408 tube bundle of methanol condensation recovery heat exchanger in a chemical company was found leaked during use. cause leakage analyzed by means macroscopic inspection, composition analysis, metallographic hardness test and fracture analysis. results show that formic acid chloride condensate are formed the exhaust gas shell side near outlet side, which spot corrosion stress cracking t...
