Summary: In recent years, heat dissipation in high heat flux devices has increased significantly, and it is expected to reach unprecedented levels in future devices. Current research focuses on the spray cooling performance and effects of a hybrid nanofluid, a thermal fluid for addressing heat dissipation issues. The results show that using hybrid nanofluid spray cooling can enhance the critical heat flux up to 126% compared to water spray cooling. This enhancement is attributed to the high latent heat of vaporization and residue wetting and wicking effects of the hybrid nanofluid.
