剪切稀化流体中气泡界面污染对传热的影响.

The stagnation cap model is used to study the heat transfer characteristics of contaminated bubbles in shear-thinning fluids. The results show that the effect of rheological index on the bubble heat transfer is relatively small but the Reynolds number and the contamination degree of bubble interface has the great influence on it; with the increase of Reynolds number and/or the decrease of stagnation cap angle, the thermal boundary layer around the bubble becomes thinner and the heat transfer becomes good; and the average Nusselt number increases with the decrease of stagnation cap angle and the increase of the Reynolds number.
