The phrase "a test section" is correct and usable in written English.
It can be used when referring to a specific part of a document, experiment, or study that is designated for testing purposes.
Example: "In the research paper, we will analyze the results obtained from a test section of the experiment to draw our conclusions."
Alternatives: "a testing segment" or "a trial portion".
The wind tunnel has a test section of 8.2 m length with cross-sectional dimensions of 1.2 m (width) × 0.85 m (height).
Such a scatterometer was constructed and installed on a test section (channel) of the RD-14M Thermalhydraulic Test Facility of Atomic Energy of Canada Limited.
The wind tunnel, which predates powered flight by 32 years, is a test apparatus in which air is blown over a model in a test section, creating an effect comparable to flight.
In a test section near Beaver Creek, at the Alaska border, researchers and engineers are also experimenting with ways to limit permafrost melting along the highway, including rock embankments that insulate the ground in summer, keeping it relatively cool, and help carry cold air below ground in winter.
A wind tunnel is built with a test section comprising a matrix of ceramic tubes.
Experiments were performed for a test section with different orifice to pipe diameter ratios (do/D = 0.25, 0.5 and 0.74).
The heat transfer performances of the nanofluid at 1% mass concentration and base fluid were experimentally determined by using an assembly, which includes a testing section based on a uniform-heat-flux boundary condition.
In this paper, dynamic measurements of fluid velocity in the by-passes of a test-section representing a nuclear fuel assembly are presented.
Static pressure measurements are taken along a test-section sidewall to provide a pressure signature of the test models under varying rotor tip-speed ratios (freestream conditions and model RPMs).
Try timing yourself when you take a practice test section (perhaps do one section a day).
Experiments were conducted in an air water two-phase flow loop with a horizontal test section.
