Fundamental Study on Thrust Deduction : 2nd Report

Abstract

In the previous report, the authors et al. have made an experimental study on the viscous effect on thrust deduction using two bodies of revolution. In the present paper, theoretical attack to the problem is attempted by solving the Navier-Stokes equation by the finite difference method with the assumption of eddy viscosity. Comparison of the calculated results with the experiments of a body of revolution shows fairly good agreement for stream lines around the body, the displacement thickness of the boundary layer, pressure distribution and thrust deduction.
