A novel technique to evaluate velocity-pressure correlation is proposed. Static pressure fluctuation is indirectly calculated from fluctuating total and dynamic pressure. The applicability is examined by the measurement in a turbulent mixing layer as well as in a wake of circular cylinder. The result is compared with directly measured fluctuating static pressure. Several statistical procedures are introduced to improve the estimated fluctuating static pressure, and it is confirmed that the correction practices is partly effective. Estimated velocity-pressure correlation with the correction practice has a similar profile to directly measured one. To obtain the quantitatively reasonable data, however, further improvement is still necessary.
