Fluctuating static pressure is closely related with fluctuating velocity in a turbulent flow, and it plays an important role in the energy balance and anisotropy of turbulence. Thus, the measurement of the fluctuating static pressure is significantly effective for the clarification of the organized structure of the turbulent flow. In this study, a static probe that is less sensitive to the yaw angle and having a good frequency response was developed, and the simultaneous measurement of velocity and pressure field was performed in a two-dimensional jet flow by a combination of this static pressure probe and an I-type hot-wire probe. In the pressure spectrum, the κ-7/3 power law range could be clearly observed, and the distribution of the cross-correlation between streamwise velocity and static pressure is demonstrated to be consistent with the previous model of coherent vortex structure.
