In this paper, the impact of micro bubbles as the second phase in the turbulent flow inside the channel flow has been investigated. The developed turbulent flow inside channel containing micro bubbles has been solved using large eddy simulation. Numerical analysis has been done to survey the impact of micro bubbles on turbulent characteristics derived from carrier flow. Finally, the mechanism of reducing frictional drag force was illustrated. According to the results, increasing the volume fraction of bubbles in the constant diameter will decrease the frictional drag force. Also studying the energy spectrum showed that the energy in the small scales has increased and in the large scales decreased.
