The phrase "a bundle of cylinders" is correct and usable in written English.
It can be used to describe a collection or grouping of cylindrical objects, often in a technical or descriptive context.
Example: "The engineer presented a bundle of cylinders that would be used in the construction of the new bridge."
Alternatives: "a collection of cylinders" or "a group of cylinders".
The structure consists of a periodic array of clusters, each constructed by a bundle of cylinders.
The electrokinetic flow of an electrolyte solution through a microchannel that comprises a bundle of cylinders is investigated for the case of constant surface potential.
Lateral components of the turbulent fluid force-per-unit-length cross-spectral densities in a bundle of cylinders are obtained by the integration of differential wall-pressure fluctuations around the circumferences of the cylinders.
Finally, the corrected method is applied to two examples of complex geometry, which cannot be simulated by standard methods using body-fitted coordinate systems without considerable difficulty: sound generation in (i) flow past an oscillating cylinder and a fixed cylinder behind it and (ii) flow past a bundle of cylinders.
The overall elastic response of a bundle of coated cylinders is a major aspect of thermal, nuclear and automotive engineering designs.
The forced convective heat transfer characteristics for incompressible power-law fluids past a bundle of circular cylinders have been investigated numerically.
The forced convection heat transfer characteristics for an incompressible, steady and Newtonian fluid flow over a bundle of circular cylinders has been investigated numerically.
The model of solution of configuration of single row of cylinders is similar to that of given by Khan et al. (2006) which the bundle of cylinders consist of a single cylinder arranged in the same distance, the same flow, and thermal characteristic around it.
In circular cylindrical coordinates, Altman and Plonsey modeled a bundle of nerves as an infinite cylinder in an infinite conducting bath, studying first the steady state [13] and transient stimulation [14].
