Abstract: In order to enhance the dynamics performance of rowing shell, a kind of polymer coating was proposed for skin friction drag reduction. The rowing shell was coated with a mixture through self-developed spray-painting system, and micro-structured polymer coating formed spontaneously on rowing shell surface after the mixture solidified. To evaluate the drag reduction property of polymer coating, comparison experiments between coated rowing shell and smooth rowing shell were performed in a deep towing tank, respectively. Experimental results showed that the skin friction drag of rowing shell with polymer coating reduced visibly. Furthermore, with the increment of rowing speed, the drag reduction performance of polymer coating became more remarkable.
Key words: rowing shell; polymer coating; deep towing tank; drag reduction
