"passage area" is a correct and usable phrase in written English.
You can use it to refer to a part of a building, structure, vehicle, or other area which allows passage from one part of it to another. For example, "We had to walk through the narrow passage area to get to the hall beyond."
Thus the annular passage area should also decrease if the through-flow velocity is to be kept nearly constant i.e., the blades have to become shorter at higher pressures.
In case of fluid flows through a continuous flow system have a non-consistent passage area such as diffuser or nozzle.
It is found that, when reducing the microchannel height, boundary layers may merge and the entrainment effect is lost, therefore the total heat flux may not always increase with a decrease of the flow passage area, as opposed to conventional microchannels.
Up until that point casualties had been relatively light with only four killed and seven wounded, but the Japanese force, which had increased overnight to between 400 to 500 men as reinforcements arrived by barges and trucks from the Buka Passage area, launched a strong attack aimed at destroying the Australian force, attacking from three sides of the perimeter.
The SN passage area and the STSL area were evaluated.
The SN passage area, ARC and AOC did not differ significantly between SSN types.
In this paper the authors present the double light pipe, an innovative technological device, designed as an evolution of a traditional light pipe, which distributes daylight to underground areas of a building, illuminating, at the same time, the passage areas thanks to a larger collector and a second transparent pipe attached to the first one.
Furthermore, the annual variation in mean passage time in the Mediterranean area was positively correlated with primary production in both departure region and passage areas in several trans-Sahara migrants [ 10].
The passage from a neritic transit area to an oceanic TRA occurred only once (PA05-4) and was associated with an increase in dive duration (Table S1).
Emin's scheme, they concluded, would fail to meet the statutory requirements to preserve or enhance the character and appearance of the Artillery Passage conservation area.
For a steady state flow of fluid flowing adiabatically through a flow system with constant passage flow area, where there were no heat or work interactions and no changes in the potential energy or elevation of the fluid, hence the stagnation enthalpy of the fluid remains constant during a steady state flow process ((h_{1}^{circ}) = (h_{2}^{circ})).
