Drag reduction plays an important role in improving the efficiency of fluid transport and
reducing the energy consumption of transport vehicles. The essential feature of bubble …

Helically coiled tube heat exchangers are the most widely used from the family of coiled heat
exchangers. This is due to their compact design, ease of manufacture and enhanced heat …

Advances in pipe transportation have contributed significantly to the application of cemented
paste backfill (CPB). However, the pressure drop during pipe transportation with complex …

The environmental risks posed by mine tailings suggest the necessity of recycling tailings as
cemented paste backfill (CPB) and constitutive modelling is an important step to understand …

Fiber-reinforced elastomeric enclosures (FREEs) generate sophisticated motions, when
pressurized, including axial rotation, extension, and compression, and serve as fundamental …

Due to their compact design, ease of manufacture and enhanced heat transfer and fluid
mixing properties, helically coiled tubes are widely used in a variety of industries and …

This review, summarises the pertinent literature on drag reduction (DR) in laminar and
turbulent flow in coiled tubes. Due to their compact design, ease of manufacture and …

To improve the selectivity and yield of multiphase reactions, an attempt to intensify gas–
liquid mass-transfer operations was undertaken in which screen/grid static mixers were used …

The hydrodynamic entrance length in helical coils for single and two-phase bubbly flow was
studied experimentally and numerically. Development region length and the detailed …

In the present paper, the effect of bubbles on the pressure drop and drag reduction of air–
water two phase flows in vertical helical coils was experimentally investigated. The curvature …
