  AF10A Multi-tube Manometer In the various experiments conducted with the AF10, it is necessary to measure pressure at several points. This AF10A multi-tube manometer consists of 14 manometers (vinyl tubes) and a reservoir, and the inclination of the manometer board can be adjusted to change the magnification.

  AF11 Bernoulli's Theorem Experimental Device Understanding how pressure changes with flow velocity in fluid dynamics is very important. The front of the 100×50mm duct is made of transparent acrylic with scales, and it comes with a removable liner to change the flow path. A Pitot tube is included to measure total pressure and static pressure along the flow, allowing for easy experimental verification and comparison of measured values with theoretical values, demonstrating Bernoulli's theorem clearly.

• 

  AF12 Air Resistance (Drag) Experiment Device It comes with test specimens of a cylinder, flat plate, and airfoil (NACA0020) that have the same projected area, and various drag forces are measured by operating a balance scale. Additionally, the included cylinder with pressure measurement holes can be connected to a manometer (sold separately) to measure the pressure distribution around the cylinder, while the Pitot tube measures the velocity distribution in the wake of each test specimen.

• 

  AF13 Round Turbulent Jet Experiment Device The jet emitted from the cylinder (diameter 51.6mm) diffuses while dragging in the surrounding air and slows down. Using the attached Pitot tube and manometer (sold separately) at several locations downstream across the jet, the velocity distribution is measured and a distribution map is created. By analyzing these, the relationships between mass, momentum, and kinetic energy within the jet can be understood.

• 

  AF14 Boundary Layer Experiment Device The fluid flowing along the surface of an object experiences a reduction in flow velocity due to viscosity, which becomes a major factor in the resistance of supersonic aircraft. The boundary layer has two distinct states: laminar flow and turbulent flow, each exhibiting completely different velocity distributions. The device includes smooth and rough plates to create different boundary layers, and the velocity distribution within the boundary layer is measured using the included wedge-shaped high-precision Pitot tube and manometer (sold separately).

  AF15 Flow Experiment Device Near the Bend Pipe When air flows through the bend pipe, the pressure increases on the outer wall and decreases on the inner wall. The bend pipe has 30 pressure ports. There are 10 ports on the outer side, 10 ports on the inner side, 9 ports at a 45-degree angle on the side, and 1 port at the entrance, which can be connected to a multi-tube manometer (sold separately) to measure the pressure at various points.

• 

  AF16 Jet Attachment and Detachment Experiment Device This device demonstrates the fundamental transition phenomena from laminar to turbulent flow, as well as the attachment and detachment phenomena occurring at solid boundaries. By rearranging the three types of nozzle blocks included, the width of the jet outlet can be changed to 5.5, 8, 10, or 12.5 mm, and the spacing between the jet and the attachment wall can also be adjusted. Additionally, by adjusting the angle of the attachment wall and opening and closing the sealing plate, it demonstrates mechanisms equivalent to a "flip-flop" switch, among others.
