Abstract
Acenaphthylene (chemical formula of C12H8, Acpy), also known as cyclopenta[de]naphthalene, is a polycyclic aromatic hydrocarbon (PAH) with 3 aromatic rings. The Acpy compound is a PAH on the Environmental Protection Agency's (EPA's) priority pollutant list. This study presents a simulation of an atmospheric plasma reactor (APR) using a method based on computational fluid dynamics (CFD). A commercial CFD tool was used to solve mass, momentum, and energy equations. The commercial FLUENT code was then used to simulate the Acpy compound using a 3D APR to treat the cooking fume exhaust emitted from a restaurant kitchen. The simulations in this study adopted the APR size and operating parameters from a self-designed atmospheric plasma reactor in a previous study (NSC95-2221-E020-021). An in-house reduced chemical mechanism was coupled with the CFD code for improved computational runtime. The reactivity of the system was considered with the RNG k-ε turbulence model and the classical Eddy Dissipation Concept combustion model. The simulation results were compared with the experimental temperature measurement and the removal efficiency of Acpy. The simulated average removal efficiency of Acpy was 61.3%.
Highlights
Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants widely distributed in the environment (Yang et al, 1998; Li et al, 2003; Lai et al, 2010; Wu et al, 2010; Bari et al, 2011; Masih et al, 2012)

Summary
Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants widely distributed in the environment (Yang et al, 1998; Li et al, 2003; Lai et al, 2010; Wu et al, 2010; Bari et al, 2011; Masih et al, 2012). The United States Environmental Protection Agency (U.S EPA) has ranked acenaphthylene the 16 priority air pollutant among polycyclic aromatic hydrocarbons (U.S EPA, 1990). The emission of acenaphthylene from cooking behaviour/activity on both air qualities and health. Chang and Hsieh, Aerosol and Air Quality Research, 13: 122–136, 2013 relevant pathological changes when the dose was 200 mg/kg/d. Toxicity data indicate absorption, and data from structurally related PAHs (primarily benzo[a]pyrene) suggest that acenaphthylene is absorbed readily from the gastrointestinal tract, lungs, and skin (U.S EPA, 1991)
