Experiment of Simplified Tower Shadow Model
Journal Title: 河南科技大学学报（自然科学版） - Year 2016, Vol 37, Issue 4
Abstract
A simplified tower shadow model was investigated by experiment. The upstream impeller was simplified into a two-dimension plate,and the downstream tower was simplified into a two-dimension cylinder.The pressure sensor and particle image velocimetry( PIV) technique were employed for the measurement of the pressure distribution on the cylinder surface and the interaction region transient velocity field data under eight plate positions. The pressure distribution on the cylinder surface,the lift coefficient,the resistance coefficient,the time-averaged velocity field and its coherent characteristics of the interaction region were analyzed. The results show that the effect of the plate on the side of the cylinder near the plate is more obvious.With the plate moving away from the cylinder,the correlation coefficient between the pressure coefficient distributions of the cylinder surface with and without the plate increases from- 0. 37 to 0. 97,and the cylinder suffered resultant force fluctuates between 72% and 115% of the original value 1. 12.
