description: This work is devoted to the computational study of the modes of water-air flow bubbling within the framework of the validation of the KORSAR calculation code. Tasks that were solved during the research: â¢ conducting experimental studies of the process of bubbling of water-air flows in vertical channels; â¢ conducting statistical processing of the experimental data obtained; â¢ analysis of the results of statistical processing for the possibility of using experimental data to validate the KORSAR calculation code; â¢ mastering the basic principles of modeling embedded in the KORSAR calculation code; â¢ development and optimization of the nodalization scheme of the experimental facility; â¢ performing calculations in the KORSAR calculation code according to the methodology used in conducting experimental research; â¢ conducting a sensitivity analysis to determine the main closing relation that affects the calculation result. The work was carried out on the basis of FSUE "Alexandrov Scientific Research Technological Institute", where a significant part of the actual material was collected: the appearance and design of the experimental installation, the results of the experiments.
