This study investigates the impact of pump blade icing on its characteristics in the working environment of power plants through numerical simulations.The icing characteristics and variations in heat transfer coefficients(HTC)were examined under different inflow temperatures and liquid water content(LWC)conditions.The results indicate a significant increase in surface icing on pump blades with decreasing inflow temperatures,leading to an increase in heat transfer coefficients.Simultaneously,an elevated LWC substantially enhances the heat transfer coefficients in the icing region,manifesting as sharp peaks in local heat transfer.By considering the combined effects of inflow temperature and LWC,the study reveals the intricate characteristics of icing in cold and humid environments.These findings provide crucial insights for a deeper understanding of the pump blade icing mechanism and the design of effective anti-icing systems.
