Abstarct: Drag force or movement inhibitor (force), has always been one of the most substantial obstacles of designing and operation of marine vehicles.There are various methods to reduce the drag force such as; using polymer solutions, hydrophobic colors and comparative coverages which all of them have disadvantages, despite advantages. One of the newest methods for drag force reduction is injection micro nano bubbles. In this research the effect of micro nano bubble on the drag force reduction phenomenon by comparing between normal water and air micro nano bubbles included water.The injection tests are done on different things and shapes such as cylinder , wedge and rectangle cube and each with 3to4 repetitions so that the results are totally reliable.The tests was used in volumetric flow rate in 4000،6000،8000،10000 liters per hour and a depth of 8،14، 18،22 cm. According to the test results، the water including air micro nano bubbles has a significant influence on physical and hydrodynamical properties of fluid and the reduction of drag force applied to the shape، which causes the reduction of drag force and coefficient of drag for each shape according to the various volumetric flow rate and section area.in the rectangular cube ، the percentage of reduction in the drag was 7/68% to 16/11% and in the cylindrical body was about 3/59% to 24/77% and in the wedge-shaped body was 14/04% to 30/97%.
