Abstract : The turbulent energy equation was investigated with particular emphasis on the mechanism of negative energyproduction. A new electronic equipment was constructed for the measurement of triple correlation terms given by uq sq and vq sq. A measuring system was developed which could produce the values of up and vp. The existing flow field was manipulated so that the regions of negative energy-production, usually very small, could be enlarged so that instrumentation could be introduced without much difficulty.
