Abstract

The previous chapter discussed the theory and the mechanisms of BLI, namely the power-saving mechanism and the body/propulsor interaction. The power balance method (PBM) was used to investigate the power conversions related to BLI. This chapter is dedicated to investigating the mechanisms of BLI through numerical simulations. The power balance method (PBM) is used to post-process the simulation data such that the detailed processes involved in the power conversion can be determined.

PK apples surface integral over the inner boundary of a CV, while the KE production rate \(\dot{{KE}_{p}}\) introduced in Chap. 3 uses surface integral over the external boundary of the CV. The two expressions of input power can be correlated as: \({P}_{K}=\dot{{KE}_{p}}+{\Phi }_{CV}\).

Total pressure is used because the jump of total pressure is identical to the static pressure jump of the actuator disc. This is related to the continuity of velocity through the actuator disc.
