The most promising solution to this challenge is the use of computational fluid dynamics(CFD) in combination with particle image velocimetry(PIV),which will be the future trend in the investigation of solar thermal systems.

Flow visualization and velocity measurement experiments on the turbulent boundary layer flow around the smooth and grooved surfaces of gyroidal objects were carried out in a towing tank by using a PIV measurement system mounted on the towing carriage.

In this paper,PIV(Particle Image Velocimetry) is applied to study the characteristic of in-cylinder flow field under different valve lifts.

Study on spiral flow in vertical pipe using the particle image velocimetry

The flow around a circular cylinder under the Reynolds numbers of 630,800 and 950 was studied experimentally by using particle image velocimetry(PIV).

The distribution of the round jet plane flow field near the spout were measured by using particle image velocimetry(PIV) at Reynolds number of 6 230 and 10 010.

2 m and two PBTs with parallel or cross arrangement have been experimentally investiga-ted by particle image velocimetry(PIV) and numerically simulated by computational fluid dynamics(CFD) using the standard k-ε model.

In this paper recently developed Particle Image Velocimetry(PIV)was used for instantaneous measurement of the full field velocity distribution in four stroke engine.
