WebJan 5, 1991 · The mixture of these two inert gases results in a relatively low Prandtl Number ({similar to}0.25). This is outside the range of the correlations used to predict the heat transfer coefficients. Therefore, tests were conducted in the laminar regime, and the results showed that the heat transfer rates were about 7% lower for Peclet Numbers (RePr) down … WebI am working on next-generation automotive solutions for connected cars, software-defined vehicles, service-oriented architectures for the future of mobility.
