Abstract Cross-drainage hydraulic structures such as culverts and bridges in urban landscapes are prone to get blocked by the transported debris (e.g., urban, vegetated), which often reduces their capacity triggers flash floods. Unavailability of relevant data from blockage-originated flooding events complex nature accumulation highlighted factors hindering research within blockage management d...
We employ a two-dimensional spectral element method to investigate the effect of various semi-circular blockages on the laminar flow between two flat plates. This simplified geometry has a general relevance to blocked flows, but more academically, also relates to work on the backward-facing step, presenting a qualitatively similar flow with a single, independent step, or blockage, parameter. Th...
A differential pressure transmitter with an orifice is widely used as a flowmeter. A major drawback of this type of flowmeter is blockage of the impulse line, which connects the differential pressure transmitter to the orifice tap. A diagnostic method based on the amplitude of pressure fluctuations in the impulse line can be used to diagnose a blockage in the steady state; however, there is the...
The process of freezing of water and blockage of pipes are summarized. Current research on freezing and its applications are briefly reviewed. Design concepts are introduced for doing work by utilizing pressures caused by ice blockage. Several conceptual designs are presented for experimental setups for the isostatic pressurization of thin walled tubes. Potential practical uses of pressures gen...
background: objective: to evaluate the effect of unilateral tubal blockage diagnosed by hsg on cumulative pregnancy rate (cpr) of the stimulated iui cycles. materials and methods: a cross-sectional analysis was performed between october 2006 and october 2009 in an academic reproductive endocrinology and infertility center. two groups of patients undergoing stimulated iui cycles were compare...
