Different criteria for selecting and optimizing the heat exchanger passage geometries were outlined by Bergles [24].
Because of the size and volume constraints in applications, such as aerospace, nuclear, biomedical engineering, and electronics, the utilization of non-circular flow passage geometries may be required, particularly, in respect of compact heat exchangers [2].
Within a class of matrices (gauzes of given weave) a single numerical parameter suffices to distinguish between flow passage geometries and, therefore, serves for the acquisition of experimental flow data and its use in support of gas path design.
For the axisymmetric contraction and expansion passages with different geometry ratios, the results obtained are compared to available constitutive models and experiments.
It was found that unit hydraulic resistance of such cartridges significantly depends upon the size of the flow passages and the geometry of the structuring gauzes, at the same, practically not depending upon the structure of the fabric and upon the external shape of the cartridge.
Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light.
Fetal head moulding is a phenomenon which may contribute to satisfactory progress during delivery as it allows the fetal head to accommodate to the geometry of the passage.
The results show the best direction to apply the impulse for each specific geometry of the passage, maximizing the gains or energy losses.
Prior to axiomatisations of the theory at the end of the 19th century, point, line, and plane were undefined concepts, with an intuitive interpretation that allowed for a ready passage between projective and Euclidean geometry.
Although it is not necessary for catalytic activity, the C-terminal domain is involved in the recognition of DNA geometry during strand passage and provides different type II topoisomerases with unique capabilities.
