Re-Establishment of Laminar Flow on a Heated Submerged Vehicle.

Abstract

In order to study the process by which laminar flow is re-established after a heated submerged vehicle encounters a patch of turbulent flow, an analytical model has been formulated which simulates the heat transfer characteristics of the external skin and internal heating passage of such a vehicle. This model considers the energy equations for the external skin and for the internal heating passage and the coupling between them due to heat transfer to the external flow. Numerical solutions to this coupled set of equations for a number of turbulent patch scenarios have been obtained by an explicit finite-difference procedure for a two-dimensional flat-plate example that quantitatively simulates the characteristics of a typical tow-tank test vehicle.
