Analysis of Flow and Pressure Drop on Tube Side of Spiral Tube Heat Exchanger under Sloshing Conditions

The utilization of the spiral tube heat exchanger (SHE) has become increasingly prevalent in large-scale liquefaction processes. However, flow pattern and frictional pressure drop two-phase have been scarcely studied, particularly under offshore sloshing conditions. An experimental system had developed to explore characteristics mixed hydrocarbon fluid a tube. Moreover, these order examine effects style (roll, pitch, heave), period (5–15 s), amplitude (5–15° or 50–150 mm), mass flux (200–800 kg/(m2·s)), vapor quality (0–1), saturation (2–4 MPa) on methane/ethane mixture results indicated that conditions reduce drop, thereby enhancing flow. A correlation was established predict factor MARD verification 6.04%. Furthermore, three boundaries were proposed based We* as an indicator.
