| Abstract: | Based on the performance characteristics of PIV (Particle Image Velocimetry) system and technical demand of measurement, a experimental system for flow field test of PDC bit is established. The configuration of the system is introduced. And the jet flow field of 4 nozzles of a PDC bit is tested by simulating the bottomhole flow field of the bit. The test result accords with the result of numerical simulation on computer. This proves the reliability of the numerical model and relevant computation methods. |
