A Numerical Method of Solution of the Problem on the Capture of Fog Particles

[摘要] It is very important, for the problem of ice formation, to investigate theoretically the paths of the fog particles near a cylindrical body exposed to wind. But it is fairly difficult to solve the equations of motion analytically, and the exact solution looks like to be obtainable only by numerical integration, say Runge-Kutta's method, starting from thg point at infinity.The author has found that the solution at sufficient distance from the body can be obtained by asymptotic expansion of x, y, u and v in terms of t, and the troubles of calculations are markedly reduced by taking the starting points of integration far nearer to the body.
