Globular clusters (GCs) provide a good environment for the formation of black hole binaries (BBHs), some of which can merge with gravitational waves (GW) within the age of the Universe. We have performed a survey of Monte-Carlo simulations to explore the impact of host GC properties on the formation and detection of BBH mergers originating from GCs. We find that the number of BBH mergers from GCs is influenced by not only the initial mass but also the initial half-mass radius and primordial binary fraction of GCs. BBH mergers can be identified by their origins, primordial and dynamical BBH mergers, significantly affecting their properties such as the mass and merging time distributions. In this talk I will provide some empirical relations like the expected number of BBH mergers from individual GCs and the time evolution of merger rates of these BBHs, which can be used to estimate the detection rates.
