Insights into the underlying reaction kinetics of gasoline–ethanol interactions and their effects on the auto-ignition characteristics of gasoline/ethanol blends

Applications in Energy and Combustion Science
Ethanol-blended gasolines show enhanced anti-knock behavior in spark-ignition engines. Fundamental experimental investigations on their auto-ignition behavior are however scarce in the literature.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Kinetic modelling of Biofuels: Pyrolysis and Auto-Ignition of Aldehydes

Chemical Engineering Transactions, 2014
Aldehydes are involved in practically all the oxidation processes of solid and liquid fuels, and they are of concern as pollutants from different combustion systems such as conventional spark-ignition gasoline engines and compression-ignition diesel engines. In the case of biofuel combustion, aldehydes are not only pollutants whose emissions have to be

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Charring Behaviour of Mass Timber: A Comparison of Thin Intumescent Coatings and Plasterboard

Fire and Materials, EarlyView.
ABSTRACT This study compares the charring behaviour of mass timber under varied heating conditions when protected by either different thin intumescent coating types or fire‐rated plasterboard layers. Bench‐scale fire experiments were conducted using the Heat‐Transfer Rate Inducing System (H‐TRIS).

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code

Journal of Raman Spectroscopy, EarlyView.
We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...
