The paper is devoted to the study of blocking force Herschel-Bulkley fluid in case steady-state flow. To this aim, we consider a mathematical model which describes flow bounded domain. We give formulation blockage phenomenon and establish existence force. also focus on behaviour with respect

CONCLUSION Blockage of the endolymphatic duct is a significant finding in Meniere's disease. The position of the utriculo-endolymphatic valve (UEV) and blockage of the ductus reuniens in the temporal bones were not found to be directly indicative of Meniere's disease. OBJECTIVE Comparison of blockage of the longitudinal flow of endolymph between ears affected by Meniere's disease and normal e...

a three dimensional, compressible, steady, one phase flow of reactant-product mixture in the air side electrode of proton exchange membrane fuel cell (pemfc) is numerically studied in this paper. the mixture is composed of three species: oxygen, nitrogen and water vapor. the performance of the cell is enhanced by partial blockage of the flow field channels. various types of these blocks also ca...

We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation ...

This study gains insight on the nature of flow blockage effects of small guidewire catheter sensors in measuring mean trans-stenotic pressure gradients Deltap across significant coronary artery stenoses. Detailed pulsatile hemodynamic computations were made in conjunction with previously reported clinical data in a group of patients with clinically significant coronary lesions before angioplast...

A numerical study is performed to investigate unsteady, two-dimensional, incompressible laminar flow over both sides of a slot-perforated flat surface, which is placed in a narrow channel. Emphasis is placed on the effect of the blockage factor, that is, the ratio of plate thickness to channel widthW on the heat-transfer performance and the velocity and thermal fields. It is found from the stud...

Administration of drugs through enteral feeding tubes can be a simple way by which infants and children can receive medications, but it introduces concerns about potential blockage of the tube. The risk of feeding tubes becoming blocked is greater with small-diameter feeding tubes and low flush volumes.Tube blockage is disruptive to patient care, and replacing tubes can be uncomfortable for the...

A push-pull ventilation system is effective for hazardous material exhaustion. Although a push-pull ventilation system has advantages over a local exhaust hood, some laborious adjustments are required. The pertinence of the adjustments is uncertain because it is difficult to evaluate the performance of a push-pull ventilation system quantitatively. In this study, a measurement of the capture ef...
