  7. Abstract:
  8. The aim of this research is to investigate the effect of speed and direction of current on ship fuel consumption. A KCS benchmark model has been numerically studied in calm water and fourteen current and wind conditions with the same speed and different directions to determine how the ship performance is dependent on flow conditions. The model has been simulated in an artificial basin propelled by a single right-handed propeller via a CFD commercial code. Numerical results revealed a linear relationship between the deviation of current and wind from head-sea or following-sea conditions and the rudder angle. The head-sea and following-sea currents and winds increased and decreased the lateral force generated by the propeller by 42% and 32%, respectively. The propeller revolution has also shown to be noticeably sensitive to current and wind. In the head-sea and following-sea conditions, this parameter indicated a 19.5% increase and a 17.8% decrease, respectively, compared to that of calm water. The required engine power to reach the target speed, which has a direct relationship with ship’s fuel consumption, has found to be decrease and increase with current and wind divergence from head-sea or following conditions, respectively. Regarding the ship’s sway motion, divergence of currents and winds from the both following-sea or head-sea conditions, linearly
    increased the sway motion
