Intermittent spray cooling is a new type cooling technology with the energy-saving advantage which can enhance the spray cooling performance and reduce energy was established consumption. In this paper, the three-dimensional simulation model of intermittent spray cooling, and it is the first time using the simulation method to study the heat transfer characteristics of intermittent spray cooling. The simulation results show that intermittent spray cooling effect can be optimized by adjusting spray cycle and duty ratio, and there is the optimal spray cycle and duty ratio at lower flow rate. The simulation results were compared with the experimental results under the same working conditions, and the calculation error was discussed, which is permitted for engineering application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
