To investigate the relationship between the structural characteristics and seepage flow behavior of
rough single rock fractures, a set of single fracture physical models were produced using the
WeierstrasseMandelbrot functions to test the seepage flow performance. Six single fractures, with
various surface roughnesses characterized by fractal dimensions, were built using COMSOL multiphysics software. The fluid flow behavior through the rough fractures and the influences of the
rough surfaces on the fluid flow behavior was then monitored. The numerical simulation indicates
that there is a linear relationship between the average flow velocity over the entire flow path and
the fractal dimension of the rough surface. It is shown that there is good agreement between the
numerical results and the experimental data in terms of the properties a of the fluid flowing
through the rough single rock fractures
