The influence of average level of refrigerant mass flux G , saturation temperature T sat , applied heat flux q , and amplitude Δ G / G and period t p of oscillating flow rate on the evaporative heat transfer of R-410A in a horizontal narrow annulus is presented. For the experimentation...
Heat transfer science is at the core of numerous industrial applications, from energy generation to electronics cooling and aerospace technologies. Innovative heat transfer techniques are becoming increasingly critical as industries continue evolving and
However, the heat transfer enhancement by SiNWs can be clearly observed after the impingement-governing area. The difference, i.e., the improvement due to SiNWs, accumulates along the wall jet region and the enhancement increases gradually as the stream flows downward. The overall distribution of...
Evaporation heat transfer in pores of porous media is analyzed in detail. The results indicate that the average heat transfer coefficient increases with the capillary pore size reduction. Under the assumption of the uniform structure of biporous media, a calculation method to predict heat transfer ...

The temperatures are quite high this summer and when the body temperature is higher than 37℃ it needs to release heat. Heat dissipation of the human body mainly happens through sweat evaporation. If the surrounding temperature is high...
The present invention relates to a kind of hollow cavities that has of evaporation heat transfer pipe, including tubular body and at least one hollow frustum structure. Outer fin, which is arranged at intervals on the outer surface of pipe between the slot between main body and radiator, forms...
The special spiral groove structure of the inner tube makes the inner tube flexible to a certain extent and does not produce the risk of frost cracking.Less risk of leakageHeat exchangers are very worried about leakage due to long-term vibration, pressure fluc...
Heat conduction, also named thermal conduction, is the heat flux in a body due to temperature difference and occurs by the movement of electrons within a body. Conduction heat transfer continues until the body reaches the thermal balance conditions. The conduction heat transfer also occurs when the...
Evaporation results in loss of heat when a liquid on a surface undergoes a phase transition into a gas. These mechanisms may be used alone or in combination to transfer heat to or from tissues, resulting in physiologic changes. Of these mechanisms, only conversion can be used to transfer ...
