The effect of operation conditions and geometrical parameters on the heat exchanger performance is investigated and main conclusions relevant for HX design are drawn as far as fin length, fin spacing, blockage ratio, gas and secondary fluid-side heat transfer coefficients are concerned.
Although this multi-row layout reduces parking space, it can cause blockage if a certain vehicle is barricaded by other vehicles and cannot leave the facility.
As a consequence, the filtrate cannot be filtered into the urinary space fast enough, causing blockages which divert the filtrate into the space between the podocyte body and foot processes.
Contrast enhancement of the area from the sacral hiatus to the epidural space performed before epiduroscopy revealed blockage of the L5/S1 vertebral area, with no contrast of the epidural space any further toward the cranial side of this area (Fig. 2a).
Classical DDT experiments were performed with the first part of the tube filled with equally spaced 75 mm (44% area blockage ratio) orifice-plates.
The dispersivity increases with increasing ROS, suggesting that the blockage of pore spaces by immobile oil globules may enhance local velocity variations and increase the tortuosity of aqueous-phase flow paths.
Severe intraocular inflammation can raise the intraocular pressure due to either the blockage of the intertrabecular space by inflammatory cells or edema of the trabecular meshwork which is the main route for aqueous drainage.
Possible explanations are highly speculative, ranging from quantum fluctuations in the vacuum of space to radiation pressure changes from the blockage of sunlight.
However, the diagnosis of adhesions located further toward the epidural space on the cranial side from the blockage requires another puncture site.
A more complex analytical model is derived to account for the considerable extra blockage which occurs when a space-frame structure is exposed to regular waves and an in-line current.
The failure of CSF flow before spinal drug administration (often known as a dry tap), is usually caused by a needle blockage, a needle in the wrong space, previous spinal surgery, or low CSF pressures [8, 9].
