Abstract:
In the frame of the Reynolds equations with SST turbulence model the numerical simulation of the energy input into the stream in front of the bow and the side surface influence on the base flow has been performed. For the regimes considered it has been shown that the energy input before the bow, resulting in a significant reduction of wave resistance has a little effect on the base pressure value. This ensures high efficiency of energy input as a mean of drag force reducing. For the considered regimes it has been shown that the investment of energy around the lateral surface leads to a small increase in base pressure.
Keywords:RANS, SST turbulence model, energy input, drag reduction, base pressure.
