No differences were observed in passive drag between the Head Down and Head in Middle at all speeds. WebJul 5, 2012 · That is because the creases lead to larger frontal area and more resistance, also small creases make an uneven surface which increases the surface resistance. Another reason is the trapped air between the creases and the manikin which increases the drag force. It shows the design of swimsuit affects the drag force acting on the swimmer. •
