Efficiency of water spraying on a heat exchanger: Local characterization with the impacted surface

•Heat transfer enhancement of water spraying is higher at low surface temperature.•A thermal image analysis is used to assess the efficient cooling surface.•The efficient cooling surface is relevant to water spraying efficiency evaluation.•The impacted surface depends on the surface temperature, not...
