Simulation study on the fluid-solid coupled heat transfer of diesel engines

To solve the heat transfer boundary problem among the piston,liner,coolant and body parts,especially the temperature and heat transfer among the coolant,liner and body.A coupled system includes the coupled flow and heat transfer between fluid and solid parts,besides coupled heat transfer among solid parts.As an example,the fluid-solid coupled system of a turbocharged diesel was brought forth.The temperature and flow fields were completed after simulation through FEA software.Comparison between simulation and measurement temperature data shows that simulation results are in good agreement with experimental data and the fluid-solid coupled method can solve the steady heat transfer among piston,liner,coolant and body of diesel engines.
