초록
A computational fluid flow analysis of a car has been accomplished to explain the lift characteristics according to the changes of wiper angle and car speed. The present study established the process to get the lift coefficient distribution on the whole range of a wiper operating angle. From the result of the present research, it could be seen that the lift coefficient of a wiper with the lower wiper angle had relatively smaller magnitude. On the other hand, the lift coefficient with the wiper angle near 45° was relatively larger than that with the other wiper angles. The present study also verified the usefulness of the lift coefficient that the lift distributions of various car speeds could be derived from the result of a lift coefficient distribution for only a car speed.
