ABSTRACT
In the present study, we are concerned with the condensation of water in a pneumatic cylinder. As the first step, the temperature and velocity distributions in the cylinder is analysed by numerical simulation assuming the flow is unsteady and two-dimentional, considering the effect of heat transfer between the air in the cylinder and the cylinder wall. Then from these distributions the time histories of temperature ticles are possibility
and velocity for some air parcalculated to examine the
of the condensation during unsteady process.
