Bubble tracer particle PIV experimental device

The invention provides a bubble tracer particle PIV experimental device which is characterized by comprising a hull opening bubble generating device and a PIV testing and analyzing device. The hull opening bubble generating device provides bubble tracer particles for the PIV experiment object, and the PIV testing and analyzing device obtains the space-time distribution of hull bubbles by measuringthe bubble tracer particles. The hull opening bubble generating device comprises a hull model, an air hole pipeline and an air source system. A cylindrical moon pool is arranged in the middle of theship body model, side thrusters are arranged on the two sides of a stem, air hole pipelines are arranged on the stem, the rear sides of the two side thrusters and the front side and the rear side of the bottom face of the moon pool respectively, and the air source system is communicated with the air hole pipelines. Compared with solid tracer particles adopted in a traditional PIV technology, the method has the advantages t
