【摘要】：為研究多壁碳納米管(Multi-walled Carbon Nanotube,MWCNT)納米結(jié)構(gòu)表面對(duì)流動(dòng)沸騰的影響,使用化學(xué)氣體沉積方法在硅表面制備多壁碳納米管納米結(jié)構(gòu)表面,并應(yīng)用于過冷流動(dòng)沸騰實(shí)驗(yàn)中,實(shí)驗(yàn)過程中采用不同的流體溫度和流體速度.結(jié)果表明,對(duì)比硅表面,MWCNT表面能夠有效地提高流動(dòng)沸騰傳熱效果,熱流密度最高提高165%;在流速為118~227 kg/m~2·s情況下,MWCNT納米結(jié)構(gòu)表面的作用效果在流速較高、加熱面溫度較高的情況下較為明顯.
[Abstract]:In order to study the effect of the surface of multi-walled Carbon nanotubes (MWCNT) nanostructures on flow boiling, the surface of multi-walled carbon nanotubes (MWCNTs) was prepared on silicon surface by chemical gas deposition, and was applied to the subcooled flow boiling experiment. The experimental results show that compared with MWCNT surface of silicon surface, the flow boiling heat transfer efficiency can be improved effectively. The maximum heat flux was increased by 165 and the surface effect of MWCNT nanostructures was better at higher flow rate and higher heating surface temperature at the flow rate of 118 ~ 227 kg/m~2 路s.
