Prediction of Body Temperature Distribution, Laminar Separation, and Transition in the Preliminary Design of Heated Underwater Bodies.

Abstract

Because of the interest in predicting the characteristics of laminar, heated, water boundary layers, an existing code was adapted for use on an IBM 370 computer and extended to include the axisymmetric case. The similar type solutions of the boundary layer equations made it possible to perform a parametric study and to use the results in developing a means for specifying a stabilizing temperature distribution on a body. Additional studies into the effect of temperature on laminar separation and transition have resulted in simplified criteria for predicting these phenomena.
