摘要:
以蒸馏水流过内径分别为168μm和399μm的不锈钢微管,研究了微管壁面温度分布和壁面轴向导热特征.依据微面热成像技术,用红外热像仪获得了恒定雷诺数和不同加热功率下微管壁面温度分布图.用一个简化的数学模型表示了壁面轴向导热和流体对流传热关系.实验和理论分析表明微管内壁面轴向导热量微小,与液体对流换热相比可以忽略.
Abstract:
Th is paper investigates the characteristics o fw a ll tem pera ture field and ax ia lw a ll heat conduction of sta in less stee lm ic rotubes w ith inner d iam eters o f 168 m and 399 m, as distilled w ater flow s through the sta inless steel m icrotube. Based on the rm al im ag ing techno logy of m icro area, the tem pera ture d istr ibu tion m aps on the w a ll o f m icro tubes a re obta ined by em ploy ing an IR Cam era fo r constant Reyno lds num ber and d ifferent heating pow ers. A sim ple m athem atic m ode l is used to express the re la tionsh ip betw een the ax ial wa ll conductive heat and the fluid convectiv e heat transfer. The exper imenta l resu lts and theoretica l ana ly sis show that the quantity of ax ia lw a ll conductive hea t is conside rably sm all and m ay be neg lected compared to the convec tive heat transfer fo r liqu id flow in m icrotube.
