  We investigate the accretion of test fluids onto regular black holes such as
Kehagias-Sfetsos black hole and a regular black hole with Dagum Distribution
Function. We analyze the accretion process when different test fluids are
falling onto these regular black holes. The accreting fluid is being classified
through equation of state according to features of regular black holes. The
behavior of fluid flow and the existence of sonic points is being checked for
these regular black holes. It is noted that three velocity depends on critical
points and equation of state parameter on phase space.
