Abstract
In this paper simulation results of two- phase flow of hydrogen are presented and
compared to measurement data of respective experimental investigations. The
aim of the simulation is the prediction of pressure losses due to different flow
conditions (e.g. mass flow rate), geometries, and heat flows (q or Tarnbient =
const.). The studies were initiated by the EU- project 'CRYOPLANE- Hydrogen
Fuelled Aircraft- System Analysis' supported within the Fifth Framework
Program of the European Commission.
The study is divided into three parts. The first part is the measurement of
pressure drops of liquidlgaseous hydrogen in a pipe with an inner diameter of 4
rnm and a total length of 3,2 m. The hydrogen mass flow and the radial heat flow
are varied. This dat
