Abstract
The two-phase jet pump is a device,
which is driven directly by thermal energy. It
simultaneously performs the functions of a
pump, a direct-contact heat exchanger, and a
condenser. The weak point for the application
of the jet pump is its low coefficient of
performance, and thus it is important to
design the jet pump such that its performance
is maximized under different operating
conditions. The present project employs the
theory of steady one-dimensional two-phase
flow with phase change, with the proper
consideration of condensation, mixing and
pressure increase, to develop a local model
for the two-phase jet pump. Such local model
contains the essential physics of the
complicated phenomenon in the jet pump,
and is more detailed than the global model in
the literature. Thus it is expected that the
present local model can provide a more solid
physical background for a proper design of
the future two-phase jet pump.
