Coefficient of overall heat transfer and Heat emissionThe authors made a beginning to develop a spherical shaped container having an internal wall constructed with ceramic hollow units for transferring molten aluminum. The newly designed container was expected to be lightweight and have high temperature...
where Ut is overall heat transfer coefficient of the whole earth tube system (W/C-m), Ta(y) is air temperature of the pipe at the distance y from the pipe inlet (°C), and ma is mass flow rate of ambient air through pipe (kg/s). Ca is specific heat of air (J/kg°C) and ...
The use of hydrophilic membrane aluminum fins improves the heat transfer wet film heat transfer coefficient and provides the overall heat transfer coefficient of the unit. U-shaped heat exchanger structure The copper tube adopts φ7.94 thread copper tube, the flow rate is moderate...
Efficient two-in-one refrigerant confluence technology improves the liquid phase flow rate of the refrigerant, improves the overall heat transfer coefficient of the heat exchanger, and improves supercooling and strengthens the refrigerant transmission di...
In comparison to traditional glass casting, glass additive manufacturing (AM) presents an opportunity to increase design flexibility and reduce tooling cos

Fig. 1(a) is a schematic diagram of the LHTES unit developed in our previous research [1,38]. The device unit has a shell and tube construction with an overall square shape and an internal heat transfer coil. We need to add fins to the coil to enhance the heat transfer between heat...
The cooling properties of oil (heat transfer coefficient and specific heat) are superior to those of air by a full order of magnitude. The Integrated Motor Pump system can therefore maintain rotor and stator winding temperatures significantly lower than those in air-cooled motors, while raising ...
Efficient refrigerant heat exchange flow path Efficient two-in-one refrigerant confluence technology improves the liquid phase flow rate of the refrigerant, improves the overall heat transfer coefficient of the heat exchanger, and improves supercooling and strengthens ...
In contrast to the metal oxide counterpart, metal halide hybrids are an emerging class of photoactive materials with tunable bandgap, high light absorption coefficient, and excellent charge transport property, showing great potentials in photovoltaics and photocatalysis23. However, the insufficient chemical...
