Hot-wire measurements have been undertaken in a turbulent boundary layer in order to examine the effect of suction applied through a short porous wall strip on the higher-order turbulence statistics. The results indicate that, although suction alters the turbulent transport of the Reynolds stresses relative to no suction, the degree of alteration differ among the turbulent transport. Similar result is observed in their recovery from the effect of suction downstream of the strip. Effect of suction is significant on skewness than on flatness factor in the near-wall region. The overall results suggest that the activity in the region near the wall is strongly interfering with by suction and the effect is increased as the suction rate increases.
