ジェット機アクロバット用着色発煙油の粘性について On the Viscosity of the Colored Smoke Oil for Jet Planes
The colored smoke trails from jet planes are generated by volatilizing colored smoke oils with hot exhaust gases from the jet engines. The colored smoke oil is a slurry, which is a mixture of selected dye with petroleum base oil. The colored smoke oil is a non-Newtonian fluid subject to the following power law. S=η' D^n where S is the shearing stress, D the rate of shear, η' the consistency index, and n the flow-behavior index. The following experimental equations were derived at low rates of shear. η'=η_0 exp (kC) (k>0) n=exp (-k'C) (k'>0) where η_0 is the viscosity of the base oil, C is the concentration of the dye, and k and k' are the constants to the kinds of dyes.
