Film Boiling Heat Transfer and Drag Reduction
Abstract
Preparations were made for turbulent film boiling tests of a heated flat plate model in the California Institute of Technology high speed water tunnel. The model and most of the support instrumentation has been assembled. The high heat flux anticipated to maintain film boiling with forced convection is produced by cartridge heaters embedded in the copper body of the model. The heater power controlers are designed to provide independent control of the heater banks in six chordwise zones. Approximate analyses of the two-phase forced-convection boundary layer flow was carried out for both laminar and turbulent flows. The analyses indicate considerable skin friction drag reduction in both flow regimes. This reduction is typically around 90 percent for water flow around a surface heater to 1000 - 2000 degrees F.
