Experimental and Numerical Study on the Plasma-Laser-Induced Ignition of Strut Stabilizer at Different Locations

Aerospace
The minimum ignition equivalence ratio of the strut stabilizer is an important parameter in the design of integrated afterburners. The ignition location significantly affects the ignition equivalence ratio and flame propagation, and therefore, it should ...

A‐optimal model‐based design of experiments for processes with uncertain inputs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Box–Behnken optimization and ANN‐ANFIS integrated modelling for transesterification using thermally activated basic oxygen furnace slag catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were

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 ...

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

Deep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.
