<div>Hi, I am working on the simulation of the Particle-Size Distribution with Pre-mixed Laminar<\/div><div>Burner-Stabilized Stagnation Flame in CHEMKIN PRO for the BSS ethylene flames (Flame C3), and I already have the chemkin input files for the BBS ethylene flame from the literature support material. However, the input files only include the gas-phase kinetic file, the thermodynamics file, and the transport file, and I need to write my own surface kinetic file. <\/div><div> <\/div><div>I am having a lot of problems writing surface kinetic file. One of them is that I am defining the lumped pseudo-species BIN1-BIN20 with the CLASS command and it is not readable by chemkin. I’ve read the 6.1.3 Particle Class of Ansys Chemkin Pro Input Manual in detail, but the application examples for CLASS are not clear and appear to be mislabeled, as in Figure 6.4. Can you please provide me with an example of the CLASS command? Preferably a definition of BIN1-BIN20 carbon soot particles.<\/div><div> <\/div><div>In addition, I see the validation of the BBS ethylene flame example in the Model Fuel Library, but the corresponding chemkin input file is garbled, can you provide the specific input file?<\/div><div> <\/div><div>Below is a surface kinetics file that I wrote myself, please correct me!
