Numerical and analytical investigation oriented ship hull wetted area like heat exchanger

Recently, Importance of energy efficiency has been realized obviously in naval architecture. Many precautions have been practiced for reduction of energy and expenditure in ship main engines. The best known examples of these applications are thermic and emission reducer precautions. Everybody knows that heat energy is the worst form of energy. Mechanical or chemical energy transform heat energy in all processes. Because of this reason to increse of energy efficiency must be used an effective thermic control.With this study, except of current sea water cooling system for jacket water cooling system of ship main engines, a new concept is designed and with this way, thermic control is done more efficiently. Disposal of sea water circuit is enable energy conservation for system configuration and maintenance. Model is examined with CFD and analytic methods, simulation of model is done appropriately, in addition, the results are obtained for three different ship speed (5,14m/s- 2,57 m/s-0,1028m/s) and nine different potential temperature ( between 0 and 40 C ) are found, these results are compared with analytic results. In conclusion, this concept is enough for required cooling load.
