Soot modeling with temperature- and size-based collision efficiency for nucleation and condensation
Applications in Energy and Combustion ScienceTemperature- and size-based collision efficiencies for the collision of dimerizing gas-phase species and for the condensation of dimers onto soot particles were estimated based on theoretical principles. These collision efficiencies were then implemented

Detailed kinetic modeling of soot formation at lightly sooting conditions
, 2017 Soot particles formed in combustion processes are well-known for their negative effects, but their formation is still elusive and challenging. In particular, the main chemical and physical pathways are not fully understood. It is important to characterize soot not only in terms of mass yield but also to accurately characterize number density and ...

Implementation of the Semi Empirical Kinetic Soot Model within Chemistry Tabulation Framework for Efficient Emissions Predictions in Diesel Engines [PDF]
, 2019 Soot prediction for diesel engines is a very important aspect of internal combustion engine emissions research, especially nowadays with very strict emission norms. Computational Fluid Dynamics (CFD) is often used in this research and optimisation of CFD

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.

Modeling Thermal Radiation in Combustion Environments: Progress and Challenges
Energies, 2023 Modeling thermal radiation in combustion environments can be extremely challenging for two main reasons. First, the radiative transfer equation (RTE), which is the cornerstone of modeling radiation in such environments, is a five-dimensional integro ...

The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...
