Краткое описание
Stabilized motion of a viscous fluid in a long plane duct with the easily penetrable roughness (EPR) over walls (i.e., a layer with a distributed mass force proportional to the local velocity) has been considered under the periodically changing pressure gradient. By means of an analytical solution in complex numbers, distributions of the velocity and shear stress have been plotted across the duct for different time moments with the absence or presence of the EPR. The influence of the EPR on the periodical flow appeared to be drastically dependent on the frequency of pressure changes. Results may be used in pneumatics or hydroautomatics, and in biological fluid mechanics.
