WAVE-CURRENT FORCES ON VERTICAL CYLINDERS IN TANDEM ARRAY FOR IRREGULAR WAVES COMBINED WITH OPPOSING CURRENT

The wave-current forces on vertical piles in tandem array induced by irregular waves with opposing current were investigated experimentally in this research. The characteristics in both time and frequency domain of inline, lift and resultant forces were also analyzed. The grouping effect coefficients of inline, lift and resultant forces on piles related to KC number and relative spacing parameters are given. These results are compared with those of irregular waves combined with following currents. It is found that the results in these two cases are quite different. The range of tested KC number is 10~60, the range of Reynolds number is (0.55~3.43) X 104.
