Abstract
A method of predicting temperature of at least one location in a fluid flow system that has a heating system for heating fluid. The method includes obtaining a mass flow rate of fluid flow of the fluid flow system, obtaining at least one of a fluid outlet temperature and a fluid inlet temperature of a heater of the heating system, obtaining power provided to the heater, and calculating temperature at the at least one location based on a model of the fluid flow system and the obtained mass flow rate, fluid outlet temperature, and fluid inlet temperature.
Claims9
A method of predicting one or more temperatures of at least one location in a fluid flow system having a heating system for heating a fluid, the method comprising:
- obtaining a mass flow rate of a fluid flow of the fluid flow system;
- obtaining at least one of a fluid outlet temperature and a fluid inlet temperature at a heater of the heating system;
- obtaining power provided to the heater;
- and
- calculating the one or more temperatures of the at least one location based on a model of the fluid flow system, wherein the model is based on the obtained mass flow rate and the fluid outlet and inlet temperatures.
