A light extinction method is adopted to determine the total soot volume (TSV) as a function of flame height and fuel mass consumption rate (FMCR). The empirical models have been built to predict TSVs of dodecane/propylbenzene (Do/PB) mixtures and aviation bio-paraffins/propylbenzene (Bio-P/PB) mixtures as the function of two variables of FMCR and concentration of propylbenzene content (%PB). TSVs of Do/PB mixtures and Bio-P/PB mixtures increase with increasing flame height, FMCR and %PB. The effect of flame height, FMCR and %PB on soot formation are respectively expressed as the quadratic, power law and linear functions. At low FMCRs, Bio-P/PB mixtures produce a slightly higher TSV than Do/PB mixtures. In contrast, at high FMCRs, the soot formations of Do/PB mixtures are slightly higher than those of their corresponding counterparts. The differences are argued to be mainly due to the remainder of a small amount of oxygenates in the bio-paraffins. It may be concluded that the aviation bio-paraffins are very similar to dodecane in respect to soot formation.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Diffusion Flame,Dodecane,Empirical model,Extinction methods,Laminar diffusion,Linear functions,Propylbenzene,Soot formations[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Aviation bio-paraffins,Diffusion wick-fed flame,Dodecane,Propylbenzene,Soot formation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The operation funds for this work have been provided by Japan International Cooperation Agency ( JICA ) under the project of ASEAN University Network/Southeast Asia Engineering Education Development Network (AUN/SEED-Net).
