Experimental Study Of The Force Of Inertia In The Difference In Rotational Motion

Aiming take the physical model test method on a horizontal rotating disc，rotating cylinderflow，binoculars concentric flow of solid single particle motion analysis. During the test usinghigh-speed cameras to capture solid single particle trajectory for the movement parameters，theuse of single-particle kinematics and dynamics model to analyze the solid single particle motioncharacteristics of the rotating flow and force law. The following conclusions：(1) Single solid particles moving in a horizontal rotary disk，If the rotary speed，the initialvelocity of the particle size，particle motion by the centrifugal force and the difference differencerotary inertia force magnitude. The direction of movement of the particles and the dial is rotated inthe same direction，the particle velocity Turn the speed dial the difference is positive，the directionof the rotary inertia force of the particles which are subject to the direction of centrifugal force andthe difference difference. The particles do eccentric exercise. On the contrary, the particles do tothe heart movement.(2) Single solid particles flow in the cylindrical rotary movement of the inner，rotating flowvelocities greater the solid single particle toward the faster the rate of tube center line offset，viceversa. Given oneu andu0can get one r0/rhave <1，At this point the difference solidsingle particle rotational inertia force suffered greater than the centrifugal force，at this point thesolid single particle movement in the tangential direction to the center, in this range of solidparticles can be completely separated single.When particles do sports to the heart，Particlessuffered difference in rotational inertia force is1orders of magnitude of the centrifugal force；(3) Solid single particle motion in the binoculars concentric flow，the inner cylinder rotation，under the conditions of the outer cylinder stationary，single solid particles by centrifugal forcelarge absolute value of the its suffered difference difference rotary absolute value of the inertialforce and the direction of centrifugal force and the difference rotary inertia force in the samedirection，the solid particles do eccentric exercise. On the contrary，the inner cylinder after the firstrotation rotation stationary outer cylinder stationary test conditions，solid particles do centripetalmovement. Solid particles in binoculars concentric rotating movement of water do to the heart，Which is subject to centrifugal force value differences rotary inertia force values an rder ofmagnitude.
