Boiling Phenomena - Comparison between CFD Simulation and Analytical Solution

Popis výsledku v původním jazyce

Boiling on heated wall under forced and natural convection is used in many industrial sectors due to large heat transfer coefficient. Boiling is typically used in the situations, where cooling of the walls with high heat fluxes is necessary. The limitation is critical heat flux. The work is based on the previous simulations for subcooled boiling (freon R12) in the heated pipe validated on the data from DEBORA experiment. This model was upgraded for saturated nucleate boiling of water and different geometry, which corresponds with the conditions occurring in the cooling device for eutectic Pb-Li17, known as cold trap. Main goal of this work was a creation of the functional CFD simulation of boiling at the heated wall and comparison of the results with analytical solution calculated by HEM model. Satisfactory agreement between the results was reached, so this acquired knowledge was used to develop the CFD model of trap device, where is Pb-Li17 eutectic cooled by water evaporation.
