ChemCatChem, EarlyView.Scaling beyond the laboratory exposes enzymes to new stresses. Exposure experiments reveal that dynamic gas‐liquid interfaces introduced by sparging or air entrainment during agitation are the main drivers of HMFO deactivation. Replacing bubbles with a membrane‐based bubble‐free aeration system dramatically enhances stability. These experiments provide

Aerodynamic investigation of an air-cooled axial-flow turbine. Part 2: Rotor blade tip-clearance effects on overall turbine performance and internal gas flow conditions: Experimental results and prediction methods [PDF]
Total turbine blade performance was investigated while changing the blade tip clearance in three ways. The internal flow at the moving blade outlet point was measured. Experimental results were compared with various theoretical methods.

Weighing risks against GHG reduction benefits in emerging green technologies
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Energy Science &Engineering, EarlyView.ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.

Effect of Sand Particle Size on Sand–Water Flow in a Francis‐99 Distributor
Energy Science &Engineering, EarlyView.ABSTRACT To examine the sand–water flow characteristics in the distributor of the Francis‐99 hydraulic turbine, numerical simulations were conducted using the Mixture multiphase flow model, focusing on the impact of varying sand particle sizes. The findings indicate that near‐wall velocities of sand and water in the fixed and guide vanes of the ...
