Abstract

Flow and heat transfer characteristics of liquid nitrogen in narrow annular channels are very important for many practical applications. In the present study, the experimental investigation of flow boiling of liquid nitrogen in narrow annular channels with gap size of 0.2 and 0.5 mm is carried out. The pressure drop and heat transfer coefficients are experimentally measured. The comparison of the theoretical models for the pressure drop and the correlations of the flow boiling to the experimental results are carried out.
