Measure by traversing the temperature boundary layer in the airflow region at intervals of 1/100 mm.
In the annular section between the inner tube and the inner and outer tubes of a double-tube heat exchanger, hot water and air are flowed under various conditions such as counterflow, parallel flow, laminar flow, and turbulent flow, capturing phenomena such as heat transfer, thermal conduction, and heat penetration numerically to aid in theoretical understanding. In particular, the temperature boundary layer within the air flow region will be measured by traversing at intervals of 1/100 mm.

Forced convection heat transfer experimental apparatus
This study examines the theory of heat transfer due to 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 32mm) 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 points on the copper pipe. The thermocouples are installed at seven locations on the outer surface of the copper pipe, three locations on the outer surface of the insulation pipe, and three locations on the inner surface of the insulation 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.
Natural and forced convection heat transfer experimental apparatus
This is a tabletop experimental device that conducts experiments on natural convection, forced convection, and heat transfer using heater modules with different surface shapes. The device consists of a duct measuring 128mm x 75mm, a removable fan, and three types of heater modules. Three thermocouples measure the temperature at the inlet and outlet of the duct, as well as the surface temperature of the heater modules. Additionally, a manual thermocouple is included to measure the surface temperature at six locations along the module from the side of the duct. The measured temperatures and wind speeds are displayed in real-time on a digital display. Furthermore, by using an optional (sold separately) data acquisition system (VDAS-B), various data can be collected and analyzed in real-time on a PC (sold separately).
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 (showing water temperature, water flow rate, voltage, and current). In the boiling heat transfer experiment, the heater wire (resistor) 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 based on 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, there are two types of finishes on the cylinder test specimen: gold plating and oxide film finishing, which reveal the differences between filmwise and dropwise 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).
