Automotive radiators - limiting performance criteria

The paper describes an experimental and theoretical study of the performance of a vehicle radiator as part of the cooling system under the limiting conditions, ie. When the coolant is likely to boil. It is concluded that the boiling of coolant will occur due to low coolant flow rather than to low air flow rate, especially in the field of low engine revolutions. The interaction between water and air flow has shown an unequal distribution of air and water flow rates in sections of the radiator. A method is outlined to determine the minimum required flow rates of water. This should lead to an optimised design, thus reducing radiator mass, cost and minimising cooling fan power requirements.
