Abstract EN
The Effective Heat Source (EHS) and Effective Momentum Source (EMS) models have been proposed to predict the development of thermal stratification and mixing during a steam injection into a large pool of water.
These effective models are implemented in GOTHIC software and validated against the POOLEX STB-20 and STB-21 tests and the PPOOLEX MIX-01 test.
First, the EHS model is validated against STB-20 test which shows the development of thermal stratification.
Different numerical schemes and grid resolutions have been tested.
A 48×114 grid with second order scheme is sufficient to capture the vertical temperature distribution in the pool.
Next, the EHS and EMS models are validated against STB-21 test.
Effective momentum is estimated based on the water level oscillations in the blowdown pipe.
An effective momentum selected within the experimental measurement uncertainty can reproduce the mixing details.
Finally, the EHS-EMS models are validated against MIX-01 test which has improved space and time resolution of temperature measurements inside the blowdown pipe.
Excellent agreement in averaged pool temperature and water level in the pool between the experiment and simulation has been achieved.
The development of thermal stratification in the pool is also well captured in the simulation as well as the thermal behavior of the pool during the mixing phase.
