Abstract The steady state heat conduction model of high temperature pipeline is established and calculated by the finite volume method. The relationship between the surface temperature distribution of the pipe and the flow rate and temperature is studied based on Levenberg-Marquardt algorithm. The effect of random measurement error on the results is studied by numerical simulation. The effectiveness of the proposed algorithm is proved and the method to reduce effect of the random error on identification results is discussed.
