The phrase "a bundle of tubes" is correct and usable in written English.
It can be used in contexts where you are describing a collection or grouping of tubular objects, such as in scientific or technical discussions.
Example: "The engineer presented a model that included a bundle of tubes designed to transport fluids efficiently."
Alternatives: "a collection of tubes" or "a group of tubes".
At the heart of these systems is the solar receiver, composed of a bundle of tubes which contain the solid suspension used as the thermal energy carrier.
The receiver consists of a bundle of tubes parallel to the mirror arrays, resulting on a smaller cross section for the same receiver width as the number of tubes increases, due to the diminution of their diameter.
In order to apply such a system to dish-solar power generation and for better absorbing concentrated solar heat, a special-shaped heater composed of a bundle of tubes was designed.
This paper presents a three-dimensional numerical and experimental geometric optimization study to maximize the total heat transfer rate between a bundle of finned tubes in a given volume and external flow, for staggered arrangements of circular and elliptic tubes.
This paper investigates the thermal performance of a prismatic slab internally cooled by a bundle of staggered tubes.
The model consists of a bundle of capillary tubes of arbitrary cross-sections, which are taken directly from photomicrographs of thin sections.
For the purpose of energy conservation and uniform heating of object surface, a gas-fired porous radiant burner with a bundle of reflecting tubes is developed.
These methods are based on the assumption of modeling porous media as a bundle of capillary tubes, ignoring many complexities associated with real porous media.
We present a bundle of triangular tubes model that simulates three-phase mixed-wet capillary pressure curves for any sequences of gas, oil, and water invasion processes.
Reported herein are the results of the experimental investigations on the effect of small amounts of heat transfer additives (Cadd<1000 ppm) on steam condensation in a bundle of horizontal tubes that are internally cooled.
In order to investigate the effect of the fins, the flooding behaviour was compared with countercurrent flow in a bundle of unfinned tubes, having almost the same cross-sectional area.
