Reynolds number and transition flow experimental apparatus

We will demonstrate the transition from laminar flow to turbulent flow and compare the critical Reynolds number in transitional flow with theoretical values. The setup consists of a glass head tank and glass tubes, an ink tank, and an injector, allowing us to observe the behavior of the flow using dye while adjusting the flow rate with a drainage valve located at the bottom of the apparatus. We will experiment on what happens when the flow transitions from laminar to turbulent. Additionally, experiments can be conducted by using an optional heater module (sold separately) to change the water temperature and viscosity.

Supersonic wind tunnel experimental apparatus

Supersonic wind tunnel experimental device

Compressed air is rapidly blown from an optional (sold separately) large-capacity compressor and tank into the downstream of the experimental area. The air that passes through the settling chamber and converging chamber provides a stable flow at subsonic, Mach 1.4, and Mach 1.8 to the experimental area. The air that has passed through the experimental area mixes again with the blown air and recirculates. Excess air is discharged from the exhaust filter. The experimental area, measuring 100mm x 25mm, comes with three types of interchangeable liners for subsonic, Mach 1.4, and Mach 1.8. The included model is mounted in the center of the observation window, and experiments are conducted while changing the angle.

Solar collector experimental device

We will conduct measurement experiments on solar thermal efficiency and heat loss regarding the use of renewable and environmentally friendly energy sources. Similar to devices used for residential heating and swimming pools, the system consists of pipes arranged on a plate, a transparent acrylic cover, a portable frame with an angle adjustment mechanism, a mixing pump, a pressure relief valve, and a control unit. The back of the plate is treated with insulation to reduce heat loss. Cold water supplied from sources such as tap water passes through a flow meter and valve, is heated by the solar collector plate, and enters the pump. The hot water discharged from the pump mixes with the supplied cold water and heads back to the solar collector plate. The pressure relief valve operates based on the water supply pressure, releasing hot water to limit the internal pressure. The control unit digitally displays the flow rate of cold water, solar radiation, cold water temperature, inlet/outlet temperatures of the solar collector plate, and ambient temperature, clarifying the energy efficiency and heat loss of the solar collector plate. By using the optional (sold separately) data automatic collection system VDAS-B, various data can be collected in real-time to a PC (sold separately), allowing for the analysis of experimental results.

HVAC-R Experimental Equipment

HVAC-R Air Conditioning System Experimental Equipment

The air conditioning systems widely used in various industries not only maintain the comfort of life but also refer to the control of industrial process environments, contributing to the improvement of living standards. The EC1550V is an apparatus equipped with an HVAC-R air conditioning system that demonstrates the thermodynamic processes of heating and humidifying, cooling, and refrigeration within ducts. The portable experimental device, using R134a as the refrigerant and equipped with movable casters, draws air from the intake grille on the left side of the duct. It passes through a manually operated damper, a variable speed axial fan, a primary heater, a steam humidifier, a heat exchanger (water-cooled), a water mist sprayer, a mist eliminator, and a secondary heater before being discharged from the exhaust grille on the right side of the duct. The temperature and humidity for each air conditioning process, the air velocity at one location within the duct, the refrigerant pressure (high and low), temperature, refrigerant flow rate, and compressor power consumption are displayed digitally. The chilled water tank, temperature-controlled by the refrigeration system, sends chilled water to the heat exchanger in the duct via a variable speed pump, and the inlet and outlet temperatures and flow rates of the heat exchanger are displayed digitally. The primary and secondary heaters, controlled by PID, can be compared in performance with different power inputs.
