The nitrogen nanobubble water circulation can be used to slow the progressions of oxidation and spoilage for the seafood long- term storage. From previous studies, a kind of honeycomb structure for high-efficiency nanobubble generation has been proposed. In this paper, the bubbly flow in the honeycomb structure was studied. The numerical simulations of honeycomb structure were performed by using a computational fluid dynamics–population balance model (CFD-PBM) coupled model. The numerical model was based on the Eulerian multiphase model and the population balance model (PBM) was used to calculate the gas bubble size distribution. The bubble coalescence and breakage were included. Considering the effect of bubble diameter on the fluid flow, the phase interactions were coupled with the PBM. The bubble size distributions in the honeycomb structure under different work conditions were predicted. The experimental results were compared with the simulation predictions., 2018 International Conference on Material Strength and Applied Mechanics (MSAM 2018) 10–13 April 2018, Kitakyushu City, Japan}, pages = {012012-1--012012-9}, title = {CFD-PBM coupled simulation of a nanobubble generator with honeycomb structure}, volume = {372}, year = {2018}, yomi = {ノダ, ナオアキ and サノ, ヨシカズ and タカセ, ヤスシ and ウメカゲ, トシヒコ} }
