中文摘要：

在小型浆体输送试验装置上系统地研究了污泥水焦浆的流变特性、滑移速度和阻力特性。采用Tikhonov正则化方法确定了水焦浆的真实流变特性和壁面滑移速度，研究了污泥添加量对水焦浆真实流变特性、壁面滑移效应、阻力特性和滑移减阻特性的影响。结果表明：水焦浆为胀塑性流体；向水焦浆中添加5％的污泥，浆体的剪切增稠特性减弱；污泥添加量达到10％时，水焦浆随剪切速率增大由胀塑性流体向假塑性流体转变。水焦浆的滑移速度随剪切速率呈加速增长趋势；污泥水焦浆的滑移速度随剪切速率呈减速增长趋势。水焦浆管道流动的阻力系数较大，污泥水焦浆的阻力系数显著降低。水焦浆的滑移减阻率随流速增大而增大，污泥水焦浆的滑移减阻率随流速增大而减小。

英文摘要：

Experimental studies were carried out on a bench-scale slurry transportation facility to investigate rheological features, wall slip and drag resistance of sludge coke slurry （SCS）. A numerical technique based on Tikhonov regularization was used to determine the true rheological characteristics and slip behavior at the pipe wall. The results show that： water coke slurry （WCS） is dilatant fluid and sewage sludge can alter its rheological properties. When mixing sewage sludge by proportion of 5% in mass into WCS, shear thickening property of the WCS is weakened. When sewage sludge proportion reaches up to 10%, WCS changes from dilatant fluid to pseudo-plastic fluid as shear rate increase. Slip velocity of WCS has an accelerating growth trend with increase of shear rate; the trend is reverse as sewage sludge is added into the WCS. Drag coefficient of WCS in pipe flow is larger than that of SCS when an amount of sewage sludge is added into the WCS. Drag reduction rate of WCS increases with ascending velocity, while that of SCS containing sewage sludge decreases with ascending velocity.
