Inverse axisymmetric body study
Abstract
A potential flow inverse body method was used to generate a family of underwater bodies that would generally possess extensive laminar flow by the use of surface heat addition. Parameters specifying the pressure coefficient distribution were varied in order to find the limits of these parameters beyond which a body could not physically be generated. Lengthtodiameter ratios and prismatic coefficients were computed as a function of the parameters. Specific cases representing the limits of parameters are used as examples in the graphical presentation of body contours and pressure coefficient distributions. Curves of temperature and heat flux distributions showing limits for the effective use of heat in suppressing boundary layer transition are also presented for these cases.
