- Abstract:
- The graphene oxide (GO) which has high thermal conductivity was mixed with water and glycol to form and the influence of the nanofluid on the heat dissipation of hydrogen internal combustion engine was studied. By comparative analysis of the change regularity for nanofluids’ thermal properties with the volume fraction of GO, while mesh generation and 3D numerical simulation for the cooling water jacket of hydrogen engine based on AVL Fire software, the information of velocity distribution, heat flux change and pressure loss can be obtained when coolant was GO-water and glycol nanofluids(the volume fraction of ethylene glycol is 10%, the volume fraction of graphene oxide were 0%, 1%, 2%, 5%). The results showed that the heat flux gradually increases and heat transfer capability evidently enhances while the concentration of nanoparticles increased, however it was caused total pressure increase between inlet and outlet in the cooling jacket and power loss of water pump also increased.
