TE78 Boiling and Condensation Heat Transfer Experimental Device
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).
