Swimming is a kind of sports. CFD (Computational Fluid Dynamics) is to analyze fluid flow numerically using computers with some discrete models. Because of movement in water, the resistance generates. In order to decrease the resistance to improve the movement efficency, in other words, to increase the swimming speed, some researchers in University of Nottingham began to use some CFD software to analyze swimming characteristics. They and some specialists in other domains, materials, manufacturing, has developed a new swimsuit which can speed up swimming, because the special material of the swimsuit can reduce the resistance when swimming. Sportsmen and sportswomen wearing it had broken several world records of swimming competition. Also, The simulation using CFD can provide some improvement advice about the motion of human body to enhance the swimming efficiency.
However, the similar research has not been done extensively in China, bionics engineering, which has been researched for a long time and achieved some good advances.
