Plots of Qa versus rd (solid) and Λ0 versus rd (dashed) for Text=1000 K,Text=1500 K,Text=2000 K,Text=2500 K, and Text=3000 K (indicated near the curves) for yellow unboiled diesel fuel. Plots shown in Fig. 2(a) are based on the values of coefficient found for external gas temperatures in the range 1000°K≤Text≤3000°K and droplet radii in the range 5≤rd≤50 μm. Plots shown in Fig. 2(b) are based on the values of coefficient found for external gas temperatures in the range 1000 K≤Text≤3000 K and droplet radii in the range 5≤rd≤100 μm.
