Graphene‐Skinned Alumina Fiber: Continuously Scalable Fabrication and Its Electrothermal Application in Fiber‐Reinforced Polymer Composites

Advanced Science, EarlyView.
Graphene‐skinned alumina fiber (GAF) is a new composite with graphene conformally grown on individual alumina fibers via chemical vapor deposition (CVD). GAF's dynamic, continuous and scalable production is achieved by using a home‐made roll‐to‐roll (RTR) CVD system featuring integrated degumming and growth chambers. GAF possesses tunable conductivity,

Wells turbine for wave energy conversion - improvement of stall characteristics by the use of 3-dimensional blades -

Journal of Fluid Science and Technology, 2014
The effect of 3-dimensional blade on the turbine characteristics has been investigated experimentally by model testing under steady flow conditions and simulated numerically by quasi-steady analysis under sinusoidal flow conditions, in order to improve ...

Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

AIChE Journal, EarlyView.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

EFFECT OF IMPELLER BLADE THICKNESS ON CRITICAL IMPELLER SPEED IN AN AGITATED VESSEL

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2017
The successful design and operation of solid-liquid agitators require proper prediction of critical impeller speed (Njs) needed to suspend solids. It depends on system and impeller geometry as well as the properties of both solid and liquid.

Assessment and calibration of the γ equation transition model for a wide range of Reynolds numbers at low Mach [PDF]

, 2017
The numerical simulation of flows over large-scale wind turbine blades without considering the transition from laminar to fully turbulent flow may result in incorrect estimates of the blade loads and performance.

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

Blade design and operating experience on the MOD-OA 200 kW wind turbine at Clayton, New Mexico [PDF]

, 1979
Two 60 foot long aluminum wind turbine blades were operated for over 3000 hours on the MOD-OA wind turbine. The first signs of blade structural damage were observed after 400 hours of operation. Details of the blade design, loads, cost, structural damage,

From Bench to Bulk: Investigating Kinetics, Recyclability, and Scale‐Up of ZIF‐67

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Zeolitic imidazolate framework‐67 (ZIF‐67), a subclass of metal–organic frameworks (MOFs), has garnered considerable attention due to its high surface area, open crystal structure, tunable porosity, and potential applications in gas separation, catalysis, and carbon capture.
