MICROCOMPUTER MEASUREMENT FOR AIR VELOCITIES IN AIR CONDITIONED ROOM.

Author(s) : MA J., AN D., LOU C.

Summary

THE AUTHORS PRESENT A NEW PROCEDURE USING A MATHEMATICAL STATISTICAL METHOD FOR THE DYNAMIC MEASUREMENT OF FLUCTUATING LOW VELOCITY TURBULENT FLOWS. THIS METHOD CAN BE SUMMARIZED AS FOLLOWS: SIMULTANEOUS MEASUREMENT OF WINDVELOCITIES AT 12 LOCATIONS ; CONTINUOUS MEASUREMENT DURING 200 SEC, TAKING 10 WIND VELOCITY DATA PER SECOND ; DATA PROCESSING BY A MICROCOMPUTER FOR OBTAINING AVERAGE AIR VELOCITY. THE FREQUENCY SPECTRUM OF INSTANTANEOUS VELOCITIES IS DEVELOPED. THE MEASUREMENT OF TEMPERATURES AT 40 LOCATIONS AND DATA PROCESSING CAN BE DONE AT THE SAME TIME AS THE MEASUREMENT OF WIND VELOCITIES.
