수면 위에서 병진 운동하는 압력에 의해 발생하는 중력-표면장력 비선형 파동

다국어 초록 (Multilingual Abstract)

Water-wave patterns generated by a pressure forcing moving with speeds close to the minimum phase speed (c<SUB>min</SUB>=23 ㎝/s) are investigated experimentally and theoretically. Four different behavioral states are observed according to forcing speeds and two transitional speeds are identified in the subcritical speed ranges. For speeds which are less than 22 ㎝/s, the patterns are simply locally depressed linear waves. For speeds between 22 and 23 ㎝/s, there exists a first transition speed, above which steady 3-D gravity-capillary solitary waves behind the forcing are observed. For speeds which are very close to c<SUB>min</SUB>=23 ㎝/s, a second transition is identified, where a periodic shedding of 3-D gravity-capillary solitary waves is observed. Finally, for speeds larger than 23 ㎝/s, a V-shaped linear wave pattern is observed. This work is an excerpted version of the present author’s past publications <SUP>(1),(2),(3)</SUP>, a part of which was also published in the Proceedings of the 7<SUP>th</SUP> National Congress on Fluids-Engineering.
