Run Up

This paper details an experimental investigation of wave run-up on a fixed vertical surface piercing circular cylinder. The study focuses on two important parameters, wave steepness and body slenderness, which are shown to influence the wave run-up. The wave steepness, kA, is varied from 0.041–0.284, and the body slenderness parameter, ka, is varied from 0.208–1.386. The zero-, first- and second-harmonic components of the wave run-up are compared with frequency based numerical predictions of the free-surface elevation by a commercially available boundary element program, WAMIT. The comparison illustrates the importance zero- and higher-harmonic contributions to the wave run-up. In particular we show that the linear diffraction prediction of the first-harmonic component is reasonable, however, the trends exhibited by the zero- and second-harmonics are not captured well by perturbation theory. Using a regression analysis, involving a separation of ka and kA dependence, the importance of higher-order wave steepness effects on wave run-up is demonstrated.

Mixer chips have wide functionality, which is not always declared by the manufacturer. The purpose of the experimental study is to prove the possibility of implementing a frequency multiplier based on the mixer chip LTC5553. An experimental study of the LTC5553 chip in the mode of frequency multiplication was performed 2, 4 and 6 times. The second harmonic transmission coefficient is not less than minus 17.25 dB, for the fourth harmonic not less than minus 35 dB, for the sixth harmonic - not less than minus 42.67 dB. The transmission power factor depends little on the input power. Recommendations for modes of using a mixer as a frequency multiplier are given.
