Probabilistic constrained Bayesian inversion for transpiration cooling
International Journal for Numerical Methods in Fluids, Volume 94, Issue 12, Page 2020-2039, December 2022., 2022 Abstract To enable safe operations in applications such as rocket combustion chambers, the materials require cooling to avoid material damage. Here, transpiration cooling is a promising cooling technique. Numerous studies investigate possibilities to simulate and evaluate the complex cooling mechanism.
