Drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. There are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. The present work aims are study on the modified drilling mud properties by using the ...

Fluid movement through the capillary membrane has been measured in the lower legs of dogs by using implanted, perforated capsules as internal plethysmographs. Utilizing this procedure it was possible to compare the effects of changes in interstitial fluid pressure with the effects of changes in venous pressure and arterial pressure on movement of fluid through the capillary membrane. A decrease...

Due to the general confusion over mask's efficiency against COVID-19 virus droplets, professionals and public may find it difficult stop disease from spreading. This study intends investigate fluid flow across N95 filtration layer based on experimental data create a simulation model analysis. Therefore, is simulated using ANSYS Fluent, part of Computational Fluid Dynamics (CFD) solver software....

In this paper, we consider a vertically positioned cylindrical filtering element. Filtering occurs in the radial direction, therefore, direction of velocities liquid and suspended particles coincide with direction. The flow can be considered to one-dimensional radially axisymmetric. To describe such process, axisymmetric Stefan problem will formulated. mass balance formalism Darcy’s law are uti...

1. Renal function in anaesthetized Brattleboro rats with hereditary hypothalamic diabetes insipidus was studied with micropuncture techniques before, and 1-3 h after, a single injection of hydrochlorothiazide. 2. In rats given hydrochlorothiazide and kept in sodium and water balance, total glomerular filtration rate and superficial nephron filtration rate were similar to values in control anima...

[1] A technique for visualizing particle transport in the interior of a porous medium is presented. The technique, which includes the construction of a translucent medium and the use of laser-induced fluorescence for particle tracking, was used to examine the behavior of a dilute suspension of negatively charged, micron-sized particles in the interior of uniform glass bead packs during one-dime...

Podocytes are specialized epithelial cells in the kidney glomerulus that play important structural and functional roles in maintaining the filtration barrier. Nephrotic syndrome results from a breakdown of the kidney filtration barrier and is associated with proteinuria, hyperlipidemia, and edema. Additionally, podocytes undergo changes in morphology and internalize plasma proteins in response ...

OBJECTIVE To evaluate the effects of four types of in-line filters on filtration rate, amphotericin B concentration and particulate matter. METHODS Filtration rates of amphotericin B fluid through in-line filters under maximum gravity flow were examined. The concentrations of amphotericin B and the particulate matter in the non-filtered and filtered amphotericin B fluid at the flow rate of 50...

In this chapter we present a new method for simulating the motion of a disperse particle phase in a carrier gas through porous media. We assume a sufficiently dilute particle-laden flow and compute, independently of the disperse phase, the steady laminar fluid velocity using the Immersed Boundary (IB) method. Given the velocity of the carrier gas, the equations of motion for the particles exper...
