| description | Hydrodynamic parametric study of the supersonic steam injection into subcooled water is
investigated.The phenomenon of direct-contact condensation, used in steam driven jet injectors, nuclear
reactor emergency core cooling systems and direct-contact heat exchangers was investigated
computationally by injecting an inclined steam jet without the presence of non condensable gases using
a supersonic nozzle submerged in subcooled water. Ansys Fluent based Euler-Euler multiphase model
is used. The angle of inclination is varied from 450 to 00 with a decrement of 200 for each computation
with the constant inlet pressure of 7 bars and water temperature of 300C. It was found that the
temperature and pressure near the nozzle exit showing an abrupt height with the instantaneous
condensation upon venting. The hydrodynamic Gaussian profile width is more in the case of vertical
injection as compare to the inclined injection which depict the effect of static water fluid pressure and
gravity on pressure head and temperature. |
