Abstract

Abstract

Based on the eigenfunction expansion technique,an analytical study on the wave generated by a piston wave generator in a depth-varied water-flume in step-type is carried out.The corresponding velocity potential and wave elevation in the flume are developed.The analytical solution is verified by a higher-order boundary element method (HOBEM).Numerical experiments are carried out to study the effect of the step on the generated wave height due to the step,the ratio of water depths at the up and low steps,the wave generator position,and the period of the wave generator motion.According to research,the suitable water depths and the wave generat or position can be chosen to reach the required wave height Meanwhile,the amplitude of the wave generator motion can be deduced according to the expected wave period and amplitude.
