PHYSICAL UNIVERSALS IN PROBLEM OF PRECURSOR SOLITON GENERATION

Six physical universals and two general relations in the problem of lo cally forced precursor soliton generation are found theoretically in t erms of the AfKdV equation derived by authors. These six universals an d two general relations are examined by experiment and numerical calcu lation of two-layer flow based on the canonical character of the coeff icients of the fKdV equations. From comparisons among the theoretical, numerical and experimental results, it is shown that they are in good agreement. There is nor any free parameter in this theory, so the the ory of the present paper can be used to predict the wave properties of locally forced precursor soliton generation.
