A thermistor-based instrument for measuring vehicle cooling airflow

Research output: Chapter in Book/Report/Conference proceedingConference PaperResearchpeer-review


This paper details the development and use of a thermistor-based instrument to measure cooling inlet airflow velocity. A 160-point instrument was used to measure flow profiles through a vehicle radiator in a full-scale automotive wind tunnel. It was found that the repeatability of the mean radiator velocity measurements was +/- 0.3% and the repeatability of the inhomogeneity of the profiles was +/- 0.4%. The effect of turbulence and flow angle on the thermistor accuracy was also considered.
