Abstract The present study aims to assess the vapour bubble absorption into the ammonia/lithium nitrate (NH3/LiNO3) solution by using an optimized CFD
model. A detailed methodology to build up the CFD model is presented, as well as its validation using experimental data. The operating conditions set
corresponds to an absorption chiller driven by low-temperature heat sources such as solar energy in warm environments. Results evidenced that the
Volume of Fluid and Mixture models are adequate to be used in the CFD model to predict the absorption process in the bubble absorber assessed
