Forced convection heat transfer experimental apparatus
This study examines the theory of heat transfer by forced convection and various formulas related to forced convection in pipes. The apparatus consists of an electric fan, a heater-equipped copper pipe covered with insulation, a measuring display, and a control panel. The air drawn in by the fan and flow control valve enters the test copper pipe (with an inner diameter of 32 mm) through an orifice. The air heated by the heater is discharged outside while passing through each measurement point. The control panel is equipped with four sets of manometers to measure the pressure loss of the fan, orifice flow rate, pressure loss in the copper pipe, and the differential pressure of the Pitot tube. Additionally, a temperature switch displays the temperatures from 14 thermocouples installed at various locations on the copper pipe.

A Pitot tube with thermocouples is also included to measure the velocity distribution in the cross-section of the copper pipe. To avoid overheating, the heater is designed to stop when the air is not flowing as specified.
Charles's Law experimental apparatus
This is a tabletop experimental device that demonstrates Charles's (Gay-Lussac's) law, which shows that the volume of an ideal gas is proportional to its absolute temperature when the pressure is constant. A pressure sensor and thermocouples (three locations) are installed in a heater-equipped adiabatic container, and each measurement data is displayed digitally. One thermocouple measures the surface temperature of the heater for control, while the other two measure the air temperature inside the container. The digital display shows the pressure inside the container, the air temperatures at two locations, and their average value. It measures the relationship between the pressure and temperature of an ideal gas (air) to demonstrate Charles's law. The device can also operate in reverse. After heating with the valve open and releasing the air inside the container, the valve is closed. Then, as the container cools down, the pressure and temperature drop are recorded. This allows for results to be obtained under various starting points and surrounding conditions. The optional VDAS automatic recording function is useful for slow natural cooling experiments. By using the optional (sold separately) data automatic collection system (VDAS-B), various data can be collected and analyzed in real-time on a PC (sold separately).

Peltier and Seebeck effect experimental apparatus
This is a tabletop device that conducts performance experiments on thermoelectric power generation using the Peltier effect, which creates a temperature difference from the voltage between dissimilar metals, and the Seebeck effect, which generates voltage from a temperature difference. In the Seebeck effect experiment, the voltage generated from the temperature difference between the cooling surface and the hot surface of the device is measured using cold water from an external source and variable electric heater output. In the Peltier effect experiment, the electric heater, water storage tank, and water supply pump are adjusted to measure the temperature difference on the device's surface. By accurately measuring the flow of water, the amount of heat transfer can be calculated, allowing for performance evaluation based on temperature gradient and power, as well as analysis of the coefficient of performance (COP) and energy balance in each mode.

Steam engine and energy conversion experimental device
You will learn about heat energy conversion and power measurement using a boiler and steam engine, as well as the basic principles of thermodynamics. Water pumped from the storage tank by the feedwater pump is superheated in the boiler and becomes steam, which drives a two-cylinder steam engine. The steam exiting the engine passes through a water-cooled condenser and enters a drainage tank or steam measurement container. A manually operated load device connected to the steam engine measures the engine's rotational speed, torque, and output, while thermocouples measure the temperature inside the boiler, the temperature of the throttling calorimeter, and the inlet and outlet temperatures of the cooling water for the condenser, displaying the results digitally. The throttling calorimeter measures the dryness of the steam based on the heat quantity. Two analog gauges display the inlet pressure of the boiler and engine, and an electric meter shows the heater power. The analysis of the Rankine cycle and verification of steam plant performance, including the Mollier diagram, clarify the relationship between pressure and temperature through boiler experiments with saturated steam. For safety, when the water level in the boiler drops and the heater overheats, the heater automatically stops, and a lamp lights up. Additionally, the boiler's safety valve limits the pressure.
Boiling and condensation heat transfer experimental apparatus
The device consists of a main unit made up of a glass container, a heating heater, a water circulation pump, a heating wire test specimen, and a water-cooled cylinder test specimen (with copper oxide surface and gold-plated surface), as well as a control unit composed of a wire temperature adjustment volume and a digital display (for water temperature, water flow rate, voltage, and current). In the boiling heat transfer experiment, the heater wire (resistance) placed inside the glass container is heated, and the transition from subcooled boiling to nucleate boiling and unstable film boiling is observed, drawing a boiling curve from the heat flux and degree of superheat. This metal wire generates high heat exceeding 100°C. In the condensation heat transfer experiment, the heat transfer due to the condensation phenomenon that occurs when steam contacts the surface of the water-cooled cylinder test specimen placed inside the glass container is measured. The heat transfer rate is derived from the temperature changes at the inlet and outlet of the water flowing through the cylinder test specimen and the flow rate. To clarify the effect of surface finishing on heat transfer, the cylinder test specimen has two types of finishes: gold plating and oxide film, revealing the differences between film and droplet condensation. By using the optional data automatic collection system VDAS-B (sold separately), various data can be collected and analyzed in real-time on a PC (sold separately).
