Abstract
In the cooling system of internal combustion engines, traditional cooling water is replaced by the water-based carbon nanotube nanofluids. To cope with the overall method of six cylinder diesel engine, the cooling system and the solid components of internal combustion engine are seen as a coupling, and the fluid solid boundary become an internal real-time boundary of nanofluids in internal combustion cooling system. In addition, heat transfer characteristics are studied in this paper. On the influence of law, different types, different volume fraction and different particle size of nanofluids have different effects on the heat transfer of internal combustion engine cooling system, which gives the coolant flow, the cooling water jacket of the heat transfer coefficient, pressure field and accurate temperature distribution. Thus, the thermal stress calculation for the internal combustion engine using water-based carbon nanotube nanofluids has laid a theoretical foundation in the application of diesel engine cooling water cavity. In this paper, the X-Y function can record the determination curve of aqueous carbon nanotube nanofluids. And then we discuss the effect of carbon nanotube content and temperature on the cooling characteristics of water carbon nanotube nanofluids. Finally, the results of experiments show that the maximum cooling rate of nanofluids increases gradually with the increase of CNT content, and the cooling performance of nanofluids decreases with the increase of quenching temperature.
