Nowadays, considering the importance of the drag reduction and increasing the speed is demand of all owners. In the field of marine industry, there should be an ongoing attempt to reduce fuel consumption of the marine vehicles. In this research, nature has been used as a guide to reach our target. Study of the skin of the fast marine’s faunas such as sharks and dolphins has generated the idea of riblet covered surfaces. Two various riblet surfaces (sawtooth and acalloped) which are studied in this research. The micro-riblets are applied on the flat plate and investigated the effects on hydrodynamics parameters through the computational fluid dynamics method in ANSYS CFX. The results have been validated with the experimental results. Based on the obtained results, the sawtooth riblet is about 11% less drag relative to the scalloped riblet.
