The pressure waves of a high-speed train in a tunnel exhibit complicated variations in their characteristics because the waves propagate and reflect with superposition. Studies have been consistently carried out on the pressure waves of a single train since changes in the area of pressure is a key element that influences ride comfort. Recently, the frequency of the operation of coupled trains has increased in order to improve the efficiency of running a train. The cross-sectional area of a…

Virtual homologation of high-speed trains in railway tunnels: A new iterative numerical approach for train-tunnel pressure signature

TLDR
A procedure for calculating the pressure variations inside the tunnel based on 3’D steady CFD simulations and a 1 D compressible fluid-dynamics model is proposed, to be used both as a design tool and for virtual homologation of new rolling stock.

CFD Simulation of a Hyperloop Capsule Inside a Low-Pressure Environment Using an Aerodynamic Compressor as Propulsion and Drag Reduction Method

One of the most restrictive conditions in ground transportation at high speeds is aerodynamic drag. This is even more problematic when running inside a tunnel, where compressible phenomena such as

Assessment methodology for pressure-related aural discomfort in high-speed trains using airtightness experiments and mathematical models

TLDR
It can be implied that large tympanic membrane and stape footplate displacements tend to elicit ear complaints, such as fullness, otalgia, and vertigo, whereas the large stapes footplate velocity affects the onset of tinnitus and hearing loss.

Comparative investigations of pressure waves induced by trains passing through a tunnel with different speed modes

Pressure waves induced by high-speed trains passing through a tunnel have adverse effects on train structures and passenger comfort. These adverse effects can be alleviated when the train passing

Review of the theory of the compression wave generated when a high-speed train enters a tunnel

Abstract A review is given of the analytical theory of the compression wave generated when a high-speed train enters a tunnel. The waveform can be calculated exactly at subsonic train Mach numbers

EXPERIMENTAL 3-D SIMULATION OF THE COMPRESSION WAVE, DUE TO TRAIN–TUNNEL ENTRY

Abstract The work presented in this paper concerns the first compression wave generated in a tunnel when a high-speed train enters it. This wave is the first of successive compression and expansion

On the role of separation in compression wave generation by a train entering a tunnel hood with a window

An approximate analytical theory is proposed for calculating the compression wave generated when a train enters a tunnel fitted with an entrance hood with an open window. The pressure rise ahead of

Aerodynamic pressures around high-speed trains: the transition from unconfined to enclosed spaces

The theory and practice of train-induced aerodynamic pressure loads on surfaces near to the tracks is compromised by an incomplete understanding of trains operating in short tunnels, partially
