Slush fluid is a two-phase (solid-liquid) single-component cryogenic fluid containing solid particles in a liquid. Its density and refrigerant capacity are greater than for liquid state fluid. In the present study, pressure drop and heat transfer characteristics of slush nitrogen flowing in a 10 mm inner diameter, horizontal heat transfer pipe were experimentally investigated with changes of mean velocity, solid fraction and heat flux. Flow patterns of slush nitrogen and the behavior of solid particles were also observed using a high-speed camera. It was found that both the pressure drop and local heat transfer coefficient of slush nitrogen are less than those of the subcooled liquid nitrogen.
