Computational Role in Thermal Engineering and Chemical Analytics During the Rotating Disk of Generalized Williamson Viscosity and Thermal Conductivity

Advanced Physics Research, EarlyView.
The schematic diagram shows the flow configuration of the model. The swirling flow of shear‐thinning materials is significantly investigated under the influence of mixed convection. In addition, heat and mass transfer flow characteristics along with gyrotactic microorganisms is also investigated. ABSTRACT Thermal conductivity, temperature gradient, and

Experimental and analytical performance investigation of air to air two phase closed thermosyphon based heat exchangers [PDF]

, 2014
In recent years, the use of wickless heat pipes (thermosyphons) in heat exchangers has been on the rise, particularly in gas to gas heat recovery applications due to their reliability and the level of contingency they offer compared to conventional heat ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Turbulent bubbly flow in pipe under gravity and microgravity conditions [PDF]

, 2012
Experiments on vertical turbulent flow with millimetric bubbles, under three gravity conditions, upward, downward and microgravity flows (1g, -1g and 0g), have been performed to understand the influence of gravity upon the flow structure and the phase ...

On investigation of capillary and pressure involved working constrains for water-driven and sintered-powder heat pipes using a semi-empirical model

Case Studies in Thermal Engineering
Heat pipes are efficient heat spreaders commonly used for thermal management in various energy and electronic systems. A heat pipe works based on phase change processes and capillary/pressure-driven circulation of working fluid. However, dryout can occur

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...
