TLDR
In this article, an analytical heat transfer model was used to develop the technology of boundary film/conduction cooled rocket thrust chambers to the space storable propellant combination oxygen difluoride/diborane.Abstract:
An evaluation of an existing analytical heat transfer model was made to develop the technology of boundary film/conduction cooled rocket thrust chambers to the space storable propellant combination oxygen difluoride/diborane. Critical design parameters were identified and their importance determined. Test reduction methods were developed to enable data obtained from short duration hot firings with a thin walled (calorimeter) chamber to be used quantitatively evaluate the heat absorbing capability of the vapor film. The modification of the existing like-doublet injector was based on the results obtained from the calorimeter firings.read more

A new generalised model for liquid film cooling in rocket combustion chambers
TL;DR: In this paper, a one dimensional analytical model of liquid film cooling in rocket combustion chambers operating at subcritical conditions is developed, which incorporates mass transfer via entrainment by adapting suitable correlations from literature pertaining to annular flow conditions.

Influence of coolant injector configuration on film cooling effectiveness for gaseous and liquid film coolants
TL;DR: In this paper, the effects of coolant injector configuration on film cooling effectiveness, film cooled length and film uniformity associated with gaseous and liquid coolants were investigated in a cylindrical test section simulating a thrust chamber.
Liquid Film Cooling in Rocket Engines
TL;DR: In this paper, a one-dimensional analytical model of liquid film cooling in rocket engine combustion chambers is developed and compared with existing data, and a standard correlation is expressed in differential form to allow for the nonuniform free-stream flow in the nozzle.
