OPTIMISING LINES DESIGN FOR BODIES OF REVOLUTION WITH ALL-TURBULENT BOUNDARY LAYERS

A mathematical formulation of bodies of revolution with permissible ranges of variation of independent shape parameters is derived from factorial and envelope analysis. A modified Head's entrainment method is used to calculate the turbulent boundary layer on the body surface and extended to the wake. By combining the concept of displacement thickness and Landweber's potential flow solution for an axisymmetric body, a computer program for obtaining the viscous drag and characteristics of turbulent boundary layers is compiled. The results obtained agree well with extensive experimental data.
