Measurement of Air Velocity Distribution and Airflow Rate Through Radiator in an Automobile

An air velocity sensor has been developed to measure the air velocity distribution at a radiator front. And, an air velocity distribution meter system for a radiator has also been developed, which can display a radiator airflow rate, a constant air velocity line graphs and a perspective representation graph, by use of many air velocity sensors mounted on the radiator front and a computer for data processing.

The airflow rate and its distribution under various running conditions for passenger car (1.8 ℓ) has been measured with the air velocity distribution meter.
