Experimental Investigation and Passive Flow Control of a Cavitating Centrifugal Pump
International Journal of Rotating Machinery, 2012 Passive flow control techniques are used to improve the flow field and efficiency of centrifugal pumps and turbomachines, in general. An important phenomenon that mechanical engineers have to take into account is cavitation.

The Gut–Heart Axis in Systemic Sclerosis: Evidence From a Large Prospective Early Disease Cohort
Arthritis Care &Research, EarlyView.Objective Cardiac involvement significantly impacts prognosis in systemic sclerosis (SSc), highlighting the need for early risk stratification. Gastrointestinal (GI) symptoms are common and often manifest early. Emerging data suggest a link between GI and cardiac manifestations, possibly through shared mechanisms like dysautonomia.

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Transition to Turbulence Delay Using a Passive Flow Control Strategy
, 2015 Since the mid–50s, until the first proof-of-concept experiment of transition delay using circular roughness elements in 2006, there was a strong consensus within the research community that roughness elements in general promoted the transition to ...

Passive flow control of Mach 4 mixed-compression intake using chevron grooves [PDF]
FME TransactionsEfficient operation of supersonic intakes is frequently hindered by shock-boundary layer interaction (SBLI), which induces large separation bubbles, pressure losses, and non-uniform flow at the engine face.

Advanced Engineering Materials, EarlyView.A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.
