Figure 12
Local hθ variation along the surface of the sphere for He gas cooling at 30 K plotted with N2 at 100 K for the same gas stream velocity, showing significant increase in hθ at all locations. Comparison shows that He gas outperforms N2 gas in terms of higher local hθ and average [\bar{h}] heat-transfer coefficients.
