Abstract: A method for determining a temperature of a fluid flowing through a pipe section includes: determining a temperature of the pipe section; obtaining a reference temperature at a distance from a surface of the pipe section; determining a heat transfer behaviour, in particular a thermal resistance, of a boundary layer of the fluid on an inner wall of the pipe section based on at least one material property and/or at least one value of a state variable of the fluid; and determining the temperature of the fluid based on the heat transfer behaviour of the boundary layer, a heat transfer behavior, in particular a thermal resistance, of the pipe section, the temperature of the pipe section, and the reference temperature.
