Calculation of Temperatures in a Water Pipe: Validation of TASEF by Comparison with Tests in a Fire Resistance Furnace

Abstract [en]

For this project the part of the software TASEF (Temeperature Analysis of Stuctures Exposed to Fire) which calculates the heat transfer through tubes, ducts or pipes has been validated. An experiment in a fire resistant furnace has been performed where a copper pipe with water flowing through it was exposed to heat on the outside. The temperature on the copper pipe was measured during the experiment as well as the temperature of the water flowing through the pipe. The temperatures from the experiment and the calculated results from TASEF were then analyzed and compared. From the experiment in the fire resistant furnace, the dimensions of the copper pipe and the boundary conditions obtained during the trials were used to construct the same arrangement in TASEF. The heat transfer coefficient between the water and the copper pipe surface used in TASEF was obtained using standard text book correlations. The magnitude of the coefficient was then used in the TASEF calculations. A parameter analysis was performed to find out what impact the emissivity of the copper pipe surface and the convective heat transfer coefficient between the water and copper pipe parameters have for the outcome of the results in TASEF. The results of the calculations and the experiments were that the water temperature measured at the exit of the copper pipe during the second trial is almost similar to the temperatures calculated by TASEF
