| Abstract: | A new compensation formula is presented to improve the measurement precision of hot wire (film) anemometer for the flow field with heat exchanging. The effect of the changes of fluid properties caused by temperature variation is considered. The compensation results of the new formula are agree well with that of the calibrating experiment while the fluid temperature is changed. |
