Stagnation point heat transfer for jet impingement to a plane surface
Abstract
A theoretical correlation is developed for predicting the stagnation point heat transfer for jet implingement on a plane surface. A closed-form solution for nozzle-to-plate spacing less than the potential flow core is obtained and shown to agree with experimental data. Consideration is also given to spacings larger than the potential flow core and a constant is defined that requires comparison with experimental data or evaluation through free-jet analysis. The results are useful for problems involving the ignition of solid-rocket motors when transient heating due to jet impingement is a factor.
