Abstract
The design and construction of a small wave tank (flume) and associated equipment has been described. The wave tank is equipped with a plunger-type wave generator, capable of producing both regular and irregular waves. A variation of the rack and pinion gear mechanism often known as the reciprocating rack mechanism is utilized to transmit power from the motor to the plunger. A triangular wedge is used as plunger in the setup. Instrumentation includes a vernier depth gauge. The wave-maker is controlled by an induction motor via a Variable Frequency Drive (VFD) or inverter drive. From the survey reports by Khalilabadi et al. of wave absorbers used in different laboratories, a beach was designed for absorbing the waves coming from wave maker. The quality of waves is improved by keeping as little room as possible behind the plunger. The main advantage of this system over previous ones is the novelty of the plunger type wavemaker and low level cost utility.
