To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...

A fundamental 2-D model was developed to predict the heat and mass transfer that occur during the frying and cooling process of tortilla chips. Semi-empirical correlations were included to account for structural changes, such as shrinkage and expansion due to puffing. All water present in the tortilla chip was considered bound and led to shrinkage when removed. The parameters that were studied ...

where Pn and Pw are the average pressures of nonwetting and wetting phases, respectively; Pc is capillary pressure, Capillary pressure plays a central role in the description of water and S is the wetting phase saturation. A schematic depicflow in unsaturated soils. While capillarity is ubiquitous in unsaturated tion of Pc vs. S curves is given in Fig. 1. analyses, the theoretical basis and pra...

Fast synchrotron-basedX-raymicrotomographywas used to image the injection of super-critical CO2 under subsurface conditions into a brine-saturated carbonate sample at the pore-scale with a voxel size of 3.64μm and a temporal resolution of 45s. Capillary pressure wasmeasured from the images by finding the curvature of terminal menisci of both connected and disconnected CO2 clusters. We provide a...

We use an harmonic technique to probe the dynamics of a liquid-liquid interface in a capillary. The capillary pressure drop induced by a harmonic displacement of the fluids is recorded as a function of the excitation amplitude and frequency. At low frequency there is an amplitude threshold above which the contact line depins and slides, and this threshold is related to the static hysteresis of ...

Currently, research on structural health monitoring systems is focused on direct integration of the system into a component or structure. The latter results in a so-called smart structure. One example of a smart structure is a component with integrated strain sensing for continuous load monitoring. Additive manufacturing, or 3D printing, now also enables such integration of functions inside com...

The association between low birth weight and high blood pressure is well established, but underlying mechanisms remain undefined. Vascular rarefaction, which may elevate peripheral vascular resistance, has been observed in capillaries of young men at risk for hypertension and men who had low birth weight. We looked for evidence that capillary rarefaction explains the association of low birth we...

INTRODUCTION Pulmonary capillary pressure (PCP), together with the time constants of the various vascular compartments, define the dynamics of the pulmonary vascular system. Our objective in the present study was to estimate PCPs and time constants of the vascular system in patients with idiopathic pulmonary arterial hypertension (IPAH), and compare them with these measures in patients with acu...

The integrity of the capillary membrane is essential to the maintenance of the circulation in a normal animal. Increased loss of plasma colloids through the capillary wall may be an important factor in the development of a pathologic state. In recent years, interest has centered upon abnormal capillary permeability, and local changes in permeability have been demonstrated in areas of trauma and...

This work explores capillary flow through micropillar arrays with rectangular pillar arrangements. The effects of these configurations on permeability and capillary pressure are investigated for heat pipe wick applications. The permeability is described in terms of three dimensionless parameters: h=d; l=d, and S=d, where l and S are the edge-to-edge spacings in the xand y-directions, respective...
