High temperature, open-cell foams fabricated by Ultramet have excellent strength, oxidation resistance, and thermal shock resistance. Because these foams yield high performance mixing with low pressure drop, they can be used within the combustion zones of rocket engines.
0.4% of the foam’s frontal area, is evenly and quickly redistributed across entire cross-section of foam sample. Effective homogenization of a flowing gas stream by Ultramet foam. Incoming gas jet, which has a cross-section of 0.4% of the foam’s frontal area, is evenly and quickly redistributed across entire cross-section of foam sample.
