An Investigation of the Drag Reduction of Underwater Vehicle by Heating

Yang Li Hua Shunfang Du Xianzhi  
The drag of undwater vehicle is usually divided into two kinds:pressure or form drag and viscous drag.They directly affect the velocity of the vehicle.The viscous drag of a slender streamlined under- water vehicle takes up a large proportion of the total drag.It might be said that how to reduce the vis- cous drag so as to increase the velocity of vehicle is the key to the problem.The drag of underwater ve- hicle can be largely reduced if the laminar portion of the vehicle hull are heated by the rejected heat of the propulsion system.This paper calculates the change of drag of a heated underwater vehicle and analyses its effects on the velocity and the energy consumption.
