The Simulation on the Resistance Plate of Rowing Based on CFD

In this article,one resistance plate is discussed,which has not affected the sports techniques and also can improve the resistance.There are also some analysis among resistance,pressures and velocities in the different attacked angles and velocities.Methods:the numerical simulation had been done using the software FlUENT 6.2,based on CFD.The resistances have been calculated in the different attacked angles.It can be seen from the simulation results that the resistance coefficients are the same under the situation of the same attacked angles and the different velocities.The variety of the velocity is much obvious than that of the attacked angles.When the angle attacked is increasing,the trends of the velocity increasing are more obvious.The resistance is referred to the square of the velocity.With the 90 attacked angles and velocity of 5 m/s,without winds,compared to the rowing weight between 155 kg and 175 kg,the resistance of the plate in 155 kg rowing is 13.33 N more than that of the adding 20 kg weight.The adding resistance is almost 2 times more than that of the weight adding.With the downwind 3 m/s,these no ascended about the resistance;with the upwind 3 m/s,the adding resistance of the plate is 44.69 N more.It is 6 times more than that of the adding 20 kg weight.It can be concluded that the drag coefficient is constant under the same attacked angle and the different velocity circumstances,while the resistance is proportional to the square of the velocity,so it is accurate that the FLUENT software for rowing resistance plate resistance calculation;the simulation results can be applied to a specific practical problems.In 90 attacked angles.The increased resistance of the resistance plate is superior to that of the rowing boat weight increasing.With the velocity increasing,the resistance is more.The resistance effect is best without changing the hull of the draft and the center of gravity.When training in the downwind,actual effect in the resistance plate is lower,when training in the upwind,it is helpful not only has the resistance plated,but also the aid of wind effect.It is very effective by using the resistance plate in this article.It can save time by the completion of the same amount of training.it also have the very practical value,thus which can improve the scientific level of training.
