The distributions of mass transfer rate and wall shear stress in sinusoidal laminar pulsating flow through a two-dimensional asymmetric stenosed channel have been studied experimentally and numerically. The distributions are measured by the electrochemical method. The measurement is conducted at a Reynolds number of about 150, a Schmidt number of about 1000, a nondimensional pulsating frequency of 3.40, and a nondimensional flow amplitude of 0.3. It is suggested that the deterioration of an arterial wall distal to stenosis may be greatly enhanced by fluid dynamic effects.
通过实验和数值模拟研究了二维不对称狭窄通道内正弦层流脉动流中传质速率和壁面剪应力的分布。采用电化学方法测量这些分布。测量在雷诺数约为150、施密特数约为1000、无量纲脉动频率为3.40和无量纲流动振幅为0.3的条件下进行。研究表明，狭窄远端动脉壁的恶化可能会因流体动力学效应而大大加剧。
