摘要：
The lift forces on horizontal cylinder near bottom is experimentally investigated at Reynolds numbers (Re) in the range of 2 500~10 000 and Keulegan~Carpenter numbers (Kc) in the interval of 5~20, and gap ratio (e/D) is from 0.2 to 1.0. Lift force coefficient (CL) and the deviation value of lift force (a0) are analyzed by using the Fourier analysis method. It is found that both CL & a0 are the functions of the Kc number.
