Abstract

This chapter presents an experimental study in order to provide experimental proof of the flow physics as discussed in the theoretical analysis in Chapter 3. More specifically, the current experimental research aims to quantify the power conversion processes involved in a propulsor ingesting body wake. Stereoscopic particle image velocimetry (PIV) has been employed for the first time to visualize the flow in wake ingesting propellers. The power balance method is used to quantify the power conversion mechanisms using the data obtained from the experiments. The results prove that the dominant mechanism responsible for the efficiency enhancement is the utilization of body wake energy by the wake ingesting propeller.

A mass-averaged velocity ( \({V}_{\bmod}=\frac{{\int}_{SP}u\text{d}S}{{\int }_{SP}\text{d}S}\)) is used to modify parameters in which V is replaced by Vmod. The modified parameters are: \({J}_{\bmod}=\frac{{V}_{\bmod}}{n\pi R}\) and \({\eta }_{p, \bmod}=\frac{T\times {V}_{\bmod}}{{P}_{w}}\).
