✦ Synopsis

The pressure drop of boiling two-phase nitrogen flow in a smoo th horizontal tube has been studied experimentally. The results show in principle the well-known dependence of the Iocal pressure drop from the vapour quality, the mass flow rate, and the heat flux.

A comparison of the measured frictionalpressure drop shows a sufficient agreement with predicted values using published correlations. The accelerational pressure gradient can also be predicted taking into account a suitable void fraction relationship.
