Abstract
A method for cooling an engine includes increasing the pressure of a liquid coolant from a first pressure to a second pressure. Thereafter, components of the engine to be cooled are contacted with the liquid coolant so that the liquid coolant at least partially evaporates and forms a vapor with a particular state. Thereafter, the vapor is fed to a throttle to reduce the pressure of the liquid coolant to a third pressure. The particular state of the vapor is determined based on the temperature and the third pressure of the liquid coolant downstream of the throttle, and based on the second pressure of the liquid coolant under an assumption that the throttle is an adiabatic throttle such that enthalpy of the liquid coolant remains constant as the liquid coolant passes the throttle. A desired vapor state adjustment is made based on the determined particular state of the vapor.
