AEROFROSH: a shock condition calculator for multi-component fuel aerosol-laden flows

“…The shock tube employed for the experimental portion of this work is that used by Haylett, MacDonald, and Campbell at Stanford, as briefly introduced in the literature review above [1][2][3][61][62][63][64][65][66][67][68][69]. Details of the algorithm that accounts for the presence of aerosol droplets are somewhat dependent on the specific experimental configuration, although the general procedure described herein is applicable to a wide variety of aerosol shock tubes.…”

“…This technique allowed for larger fuel loading than some previous experiments, but one drawback of this turbulent mixing strategy was that the aerosol droplet number density throughout the tube was not uniform. This work was continued by Haylett, MacDonald, and Campbell, who measured fuel ignition delay times and studied reaction kinetics behind reflected shocks in aerosol mixtures [1][2][3][61][62][63][64][65][66][67][68][69]. Their fuel-loading procedure involved producing a tank of aerosol using nebulizers and then drawing this mixture into the tube through a sliding endwall gate valve in a laminar plug flow.…”

“…Adaptations to this algorithm that allow the use of multi-component fuel aerosols will be introduced as well. Such adaptations are particularly important for experiments involving biodiesel fuel [1,2], which consists of a blend of five primary constituents, or jet fuels like JP-8/Jet-A [3]. Finally, an in-depth uncertainty analysis for this code's calculations will be presented.…”

A second-generation constrained reaction volume shock tube

“…By this method, shock tube researchers can avoid using extreme mixing tank and shock tube heating in order to increase the fuel vapor pressure and generate enough fuel vapor for experimentation, as has been done historically. [36][37][38] Such heating is problematic because it can introduce issues of partial fuel distillation and pre-experimental fuel decomposition. 16 Figure 11 applies Eqs.…”
