“…With the development of computational fluid dynamics and computational combustion and the dramatic increase of computer computing power, the numerical simulation of engine combustion has been rapidly developed and has been able to predict the two-dimensional, constant, viscous flow field in the combustion chamber as well as the three-dimensional, constant, viscous complex flow [1,2]. In-cylinder combustion is turbulent combustion, and turbulence plays an important role in heat and mass transfer during combustion, while the chemical reaction can be generated and the reaction rate is influenced by the reaction mechanism itself, such as temperature, substance concentration, etc.…”

The combustion process of a dual‐fuel engine was calculated by characteristic timescale model (CTM), eddy breakup model (EBM), and coherent flamelet model (CFM) to verify the accuracy of the combustion models. The results show that the peak pressure calculated by EBM is 2.78 % higher than the experimental value, and the peak pressure calculated by CFM is closest to the experimental value. The EBM is the most accurate for CO2 emissions. The deviation of CO emissions from the experimental values calculated by CTM is the smallest (< 1 %). The NOx emission calculated by CTM is good agreement with the experimental value at low speed, and EBM is in best agreement with the experimental value at high speed. The hydrocarbon emission calculated by CFM is the most accurate, with a deviation of less than 0.6 %.

“…In addition, carbon monoxide (CO), hydrocarbons (HC), and nitric oxide (NOx) from the incomplete combustion of gasoline also have a significant environmental impact. Current research on the reduction of environmental pollution from fuels has focused on the use of biodiesel and gasoline blends [23] and exhaust gas catalysts [24][25][26].…”

The GHG Emissions Assessment of Online Car-Hailing Development under the Intervention of Evaluation Policies in China

To assess the impact of the online car-hailing services on the environment in China, in this paper, we develop a model to evaluate greenhouse gas (GHG) emissions and emission reduction during the production and use of car-hailing, as a result of increased online bookings. Since energy use differs according to type of vehicle, this paper also contains different scenarios that depict degrees in the regulation stringency according to the Chinese Preliminary Rules on the Management of Online Car-Hailing, regional differences, and development of electric vehicles. The results show that, under the three different scenarios, the online car-hailing service would have the highest GHG emissions of 325, 413, or 160 MtCO2 and the highest reduction in emissions of 19.46, 25.1, or 9.48 MtCO2 by 2030. The government needs to encourage the development of online car-hailing to reduce the purchase of private cars, avoid compulsory actions to shut down online car-hailing platforms, and mandate that only electric vehicles (EVs) can be used for online car-hailing.

“…To the best of the authors' knowledge, the interaction between reaction and multiphase fluid dynamics in JLR as well as in similar reactors has not been systematically studied in the literature. The reaction is indeed frequently included in the calculation [23][24][25][26][27], but a systematic investigation and the effect on the operating behavior and reactor design is mostly missing. This is the gap we would like to close with our model and parameter studies.…”

Model-Based Investigation of the Interaction of Gas-Consuming Reactions and Internal Circulation Flow within Jet Loop Reactors

2022

Jet loop reactors are standard multiphase reactors used in chemical, biological and environmental processes. The strong liquid jet provided by a nozzle enforces both internal circulation of liquid and gas as well as entrainment and dispersion of the gas phase. We present a one-dimensional compartment model based on a momentum balance that describes the internal circulation of gas and liquid phase in the jet loop reactor. This model considers the influence of local variations of the gas volume fraction on the internal circulation. These local variations can be caused by coalescence of gas bubbles, additional gas-feeding points and gas consumption or production. In this work, we applied the model to study the influence of a gas-consuming reaction on the internal circulation. In a comprehensive sensitivity analysis, the interaction of different parameters such as rate of reaction, power input through the nozzle, gas holdup, reactor geometry, and circulation rate were investigated. The results show that gas consumption can have a significant impact on internal circulation. Industrially relevant operating conditions have even been found where the internal circulation comes to a complete standstill.
