Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide
The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5954-5978, November 2026.Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine
Wind Energy, Volume 29, Issue 11, November 2026.ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

Aerodynamics of an airfoil with leading‐edge icing
Wind Energy, 2021 The flow over the leading edge of an NREL S826 reference airfoil with three different icing‐inspired leading‐edge contamination geometries has been assessed experimentally. Particle image velocimetry was performed on the leading edge of the airfoil for a

Prediction of Self‐Starting of a Vertical Axis Wind Turbine Using Static Torque
Wind Energy, Volume 29, Issue 11, November 2026.ABSTRACT The ability of vertical axis wind turbines (VAWTs) to self‐start is critical to their performance. There is disagreement in the literature over some of the factors affecting their self‐starting ability and there is very limited information on how the starting azimuthal angle affects self‐starting. We present a series of wind tunnel experiments

NUMERICAL INVESTIGATION OF TWO ELEMENT CAMBER MORPHING AIRFOIL IN LOW REYNOLDS NUMBER FLOWS [PDF]
Journal of Engineering Science and Technology, 2017 Aerodynamic performance of a two-element camber morphing airfoil was investigated at low Reynolds number using the transient SST model in ANSYS FLUENT 14.0 and eN method in XFLR5. The two-element camber morphing concept was employed to morph the baseline

Dynamic Stall Characteristics of the Bionic Airfoil with Different Waviness Ratios
Applied Sciences, 2021 A dynamic stall will cause dramatic changes in the aerodynamic performance of the blade, resulting in a sharp increase in the blade vibration load. The bionic leading-edge airfoil with different waviness ratios, inspired by the humpback whales flipper ...

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.ABSTRACT Dimensionality reduction is essential in simulation‐based shape design, where high‐dimensional parameterizations hinder optimization, surrogate modeling, and systematic design‐space exploration. Parametric Model Embedding (PME) addresses this issue by constructing reduced variables from geometric information while preserving an explicit ...
