Validation of Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water

<div>(a) Vertical temperature distribution in STB-21 test, (b) measured steam flow rate, (c) part of data simulated with EHS-EMS models, and (d) corresponding imposed heat fluxes that change from the pipe’s submerged surface to the pipe’s exit. Phase A: first mixing. Phase B: onset of stratification. Phase C: stratification. Phase D: onset of second mixing. Phase E: second mixing followed by stratification.</div>
