Leakage flow simulation in a specific pump model [PDF]

open access: yes, 2014
This paper deals with the influence of leakage flow existing in SHF pump model on the analysis of internal flow behaviour inside the vane diffuser of the pump model performance using both experiments and calculations. PIV measurements have been performed

Journal diffusion factors – a measure of diffusion? [PDF]

open access: yesAslib Proceedings, 2004
This paper shows that the measure of diffusion introduced by Ian Rowlands called the journal diffusion factor (JDF) is highly negatively correlated with the number of citations, leading highly cited journals to get a low JDF, whereas less cited journals get a high JDF.

Diffusion nets

open access: yesApplied and Computational Harmonic Analysis, 2019
Non-linear manifold learning enables high-dimensional data analysis, but requires out-of-sample-extension methods to process new data points. In this paper, we propose a manifold learning algorithm based on deep learning to create an encoder, which maps a high-dimensional dataset and its low-dimensional embedding, and a decoder, which takes the ...

Multilevel Diffuser Augmented for Horizontal Axis Wind Turbine

open access: yesE3S Web of Conferences, 2018
Indonesia is an area with the low and fluctuating wind speed. Therefore, the implementation of the wind turbine to generate electricity become ineffective and economically unprofitable.

Reaction-diffusion processes with nonlinear diffusion [PDF]

open access: yesPhysical Review E, 2012
We study reaction-diffusion processes with concentration-dependent diffusivity. First, we determine the decay of the concentration in the single-species and two-species diffusion-controlled annihilation processes. We then consider two natural inhomogeneous realizations.

Numerical Studies of Curved-walled Micro Nozzle/Diffuser [PDF]

open access: yes, 2010
In this study, commercially available software CFD was adopted for analyzing the performance of straight-walled and curved-walled micro nozzle/diffuser. Such nozzle/diffuser was used in valve-less micro-pumps.
