The present experimental study was performed to explain the effects of the couple interaction between wave and current over a pair of hemispheres. Probability density function for the velocity fluctuation was analysed to explore the response of a surface wave on the following current. The external forcing effects of the hemisphere and superimposed surface waves within the main flow field are capable of modulating the entire range of turbulent eddy scales, and have an essential role in the modulation of the distribution of different eddy scales in the frequency domain.

Abstract


The present experimental study was performed to explain the effects of the couple interaction between wave and current over a pair of hemispheres. Probability density function for the velocity fluctuation was analysed to explore the response of a surface wave on the following current. The external forcing effects of the hemisphere and superimposed surface waves within the main flow field are capable of modulating the entire range of turbulent eddy scales, and have an essential role in the modulation of the distribution of different eddy scales in the frequency domain.
