Effect of UHMWPE Incorporation on the Tribological Performance of Carbon fiber‐Reinforced PEEK Nanocomposites

Journal of Applied Polymer Science, EarlyView.
UHMWPE provides interfacial lubrication, improving tribological performance of PEEK‐based sliding bearing bushings. ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) was incorporated into a PEEK‐based hybrid material as a lubrication additive to improve the friction and wear performance of the composite due to its superior lubricity ...

NEW NUMBER NUSSELT CORRELATION FOR THE ANNULAR SPACE OF THE TUBE IN TUBE HEAT EXCHANGER [PDF]

The use of Nusselt number correlation in the annular space of a tube-in-tube heat exchanger is a difficult task for researchers, since this correlation is deduced specifically for certain geometrical features.

Use of Fin Equation to Calculate Nusselt Numbers for Rotating Discs [PDF]

Volume 5C: Heat Transfer, 2015
Conduction in thin discs can be modelled using the fin equation, and there are analytical solutions of this equation for a circular disc with a constant heat-transfer coefficient. However, convection (particularly free convection) in rotating-disc systems is a conjugate problem: the heat transfer in the fluid and the solid are coupled, and the relative

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

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.
