Abstract:

I. A modeling techni ue for measuring the velocity components of air surroundi g a f lli g cloud drop is described. T H DROP IS MODELED BY SUSPENDED BRASS SPHERE WHICH IS LOWERED AT A CONTROLLED RATE THROUG A VISCOUS FLUID. A preplaced trac r line of black ink drops is p o ographed as it describes the position of a fluid streamline around t phere. II. An analysis is made of the penetra ion of a water drop into a plane water surface under the assumption that a t in gaseous film separates the two liquid surfaces The p netration equation is rit en in terms of a coalescence parameter pi sub c. The ratio of pe etration to drop diameter is a cons ant in t e restricted range in which pi sub c is a constant. III Instru entatio is described which permits the study of a succession of colliding liquid drops. The desig permit free adjustment of the drop size , i pact ngles, and velocities. Author
