Incorporating Nucleate Boiling in a Precision Cooling Strategy for Combustion Engines 971791
Precision cooling has a number of advantages over the conventional cooling of combustion engines. It is primarily used to prevent component failures and is generally intended to create an even distribution of temperature within the cylinder head and block. This leads to lower thermal stresses and higher component durability.
Precision cooling in the form of forced convection and nucleate boiling can be used to greater effect than that of traditional precision cooling concentrating on forced convection only.
This paper describes the analytical and experimental precision cooling strategy that has been used to investigate nucleate and transition boiling. Analytical details of the models are described and preliminary experimental data is provided for comparison.
The major finding indicates that the diameter of the internal cooling passage is one of the significant factors that influences the critical heat flux.
