Gaussian integral method for void fraction

Particuology
A novel method, the Gaussian Integral Method (GIM), is presented for calculating void fractions in Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) simulations. GIM is versatile and applicable to various grid types, including structured and unstructured polyhedral meshes, without requiring special boundary treatments.

Void fraction measurement in cryogenic flows. Part II: Void fraction capacitive sensor performances in chilldown experiments [PDF]

Cryogenics, 2018
Abstract This manuscript describes the work performed on void fraction measurements a cryogenic flow by means of a customized capacitive sensor. In a preceding activity, described in Part I, the instrument was developed and validated at room conditions.

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Simultaneous capacitive probe and planar laser-induced fluorescence measurements in downwards gas-liquid annular flow [PDF]

, 2017
Various experimental techniques are available to analyse two-phase flows. The measurement concept and the applicability can however vary greatly. Prime examples from the opposite spectrum are planar laser-induced measurements (PLIF) versus capacitive ...

Spectral Properties of Galaxies in Void Regions

, 2015
We present a study of spectral properties of galaxies in underdense large-scale structures, voids. Our void galaxy sample (75,939 galaxies) is selected from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) with $\rm z < 0.107$. We find that there

Pressure drop and average void fraction measurements for two-phase flow through highly permeable porous media [PDF]

, 2016
The modeling of pressure drop for two-phase flows through porous media is a key point to assess the coolability of debris beds resulting from nuclear severe accidents. Models involve several parameters which are non-linear functions of the void fraction,

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Review and Evaluation of Slip-ratio-based Void Fraction Prediction Models

Yuanzineng kexue jishu
Void fraction is an important parameter in gas-liquid two-phase flow, which is closely related to the flow pattern, pressure drop, and heat transfer of the flow field.

ECT and LS-SVM Based Void Fraction Measurement of Oil-Gas Two-Phase Flow [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2010
A method based on Electrical Capacitance Tomography (ECT) and an improved Least Squares Support Vector Machine (LS-SVM) is proposed for void fraction measurement of oil-gas two-phase flow.
