Monopile response to scour and scour protection
, 2020 Scour of seabed sediments can occur around offshore structures, the resultant reduction in strength and stiffness of the structure’s foundations presents operational challenges for monopile-supported offshore wind turbine structures. Turbines are at risk of reduced operation or even premature decommissioning if scour causes the natural frequency of a ...

The Canadian Journal of Chemical Engineering, EarlyView.Polymeric and molecular amines embedded in hygroscopic matrices to facilitate CO2 transport for CO2/H2 separation. Abstract This work dealt with composite membranes comprising of polyvinylamine (PVAm) and triethylenetetramine (TETA) embedded in poly(vinyl alcohol) (PVA) for CO2/H2 separation via facilitated transport of CO2, where polymeric and ...

Laboratory Study of Local Scour Around an Array of Pile Groups in Clear-Water Scour Conditions
Journal of Marine Science and EngineeringCurrent-induced local scour around pile groups weakens the capacity of structures. In this paper, experimental tests of local scour around an array of 5 × 5 pile groups were conducted in a steady current in a hydraulic flume.

Scour‐control and scour‐resistant design for hydraulic structures [PDF]
Eos, Transactions American Geophysical Union, 1942 There now exists in theoretical analyses, in laboratory findings, and in conventional engineering‐design practice, a skeleton of facts on which a rational scour‐control procedure can be based. The writer has assembled these facts and stated them in as straightforward a manner as he believes, in consistent with current knowledge.

The Canadian Journal of Chemical Engineering, EarlyView.Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

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 ...

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.
