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 graph 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 script l) has been measured with the air velocity distribution meter. /SASI/

AUTOMOTIVE MIXED FLOW FAN WITH GUIDE VANES ON BLADE SURFACES

We have developed a simple and lower cost mixed air flow fan with guide vanes on the blade surfaces for use in automotive engine cooling. Through investigation of the fan performance and flow visualization, the axial and radial flow produced by this fan proved to be most suitable and efficient for engine cooling. The improved efficiency and increased air flow provided by this fan contribute to reduction of specific noise level and power consumption as compared to conventional fans.
