Abstract

The invention provides a Magnus effect demonstration instrument. The Magnus effect demonstration instrument includes a housing supporting structure, and an air supplying mechanism and a swing device are arranged in the housing supporting mechanism, wherein the air supplying mechanism is arranged at the upper portion of the housing supporting structure; the swing device is arranged under the air supplying mechanism; the swing device comprises a cylinder, a first motor, a hoop and a swing rod assembly, and the first motor is arranged in the cylinder and is coaxial with the cylinder so that the cylinder can be driven to rotate coaxially; one end of the hoop is rotatably connected with the motor, and the other end of the hoop is connected with the swing rod assembly. The Magnus effect demonstration instrument has the advantages that the public can know the scientific knowledge about hydromechanics and understand the life phenomena including why a ball will deflect in the motion process in combination with examples in life, and the public are encouraged to love and explore science.

Description

technical field [0001] The invention relates to a demonstration device in the field of fluid mechanics, more specifically, to a Magnus effect demonstration instrument for researching and demonstrating the movement of objects in airflow. Background technique [0002] The Magnus effect is an important law in fluid mechanics. This effect is mainly manifested as: when the rotational angular velocity vector of a rotating object does not coincide with the flying velocity vector of the object, a lateral force will be generated in a direction perpendicular to the plane formed by the rotational angular velocity vector and the translational velocity vector. The phenomenon that the flight path of an object is deflected under the action of this lateral force is called the Magnus effect. From a physical point of view, the reason why a rotating object can generate force in the lateral direction is that the rotation of the object can drive the surrounding fluid to rotate, so that the flui...
