As can be seen in Fig. , for 𝐵 < 0.038 and |Da ef | < 1.5, there is excellent agreement between the results of the two methods. The maximum relative error was 0.17%, 0.04%, and 6.3% for the particle temperature, fluid temperature, and conversion, respectively. As illustrated in Figure , the following variations are also observed in the calculations: 14.8 × 10 0R < Th M < 10.3 and 99.0 × 10 0R < Py 7 < 68.5 × 10 M .
