As the speeds of both passenger and freight trains increase, there is increasing concern that unsteady gusts generated in train boundary layers wakes will become more for a risk to passengers waiting on platforms trackside workers. In addition, demands interoperability make this problem growing relevance railway operators across Europe. A number model scale full-scale experiments have been carried out recent years provided robust experimental data quantify these flows. This paper considers...
This paper describes the derivation of a simple yet realistic engineering model tornado wind and pressure fields. novel is shown to be capable providing method for predicting speed time histories debris impact energies that can ultimately used in development rational risk-based design methodology loads on buildings. A stationary one-cell vortex first considered, circumferential vertical velocities profiles derived from assumption radial velocity (that bounded directions) use Euler equations....
The distribution of boundary shear stress in circular conduits flowing partially full, with and without a smooth flat bed simulating deposited sediments, has been examined experimentally ranging from 0.375 < F 1.96 6.5 × 104 R 3.42 105, using the Preston tube technique invert level water depth have varied to simulate wide range possible flow conditions that may occur culverts, sewers, hydropower tunnels. around wetted perimeter is shown be highly sensitive changes cross-sectional shape....
Abstract Lodging resistance ratings for winter wheat cultivars are frequently based upon observations of lodging. This is an unreliable method because the frequent occurrence years without significant lodging events. It also does not distinguish between stem and root resistance. paper describes development testing instrumentation procedures two field‐based methods to rapidly assess Both used a specifically designed instrument measuring shoots against rotational displacement. Stem was...
Building on previous work where fluorescence spectroscopy has been used to detect sewage in rivers, a portable LED spectrophotometer was for the first time establish bacterial numbers range of water samples. A mixed-method approach with standard bacteria enumeration techniques diluted river and works final effluent using number diluents (Ringer's solution, tap potable spring water). Fluorescence from uncultured dilutions detected at 280 nm excitation/360 emission wavelength (corresponding...
Increases in the volume of trade within UK rail freight industry have led to proposed increases train speeds. There is a concern that unsteady slipstream created around moving could implications on efficiency and safety passengers waiting platforms or trackside workers. This paper describes series model-scale experiments conducted at University Birmingham’s TRAIN rig facility. Experiments were undertaken assess development container draw conclusions flow characteristics. In this term...
Having been identified as the cause of design load winds in many parts world, transient such gust fronts and thunderstorm downbursts have increasingly researched over recent years. The difficulties simulating flow structure laboratory, particularly their rapid radial acceleration associated ring vortices, complicated measuring wind loads on structures subject to these conditions. University Birmingham Transient Wind Simulator (UoB-TWS, a 1 m diameter impinging jet with aperture control) has...
Abstract Lodging in barley ( Hordeum vulgare L.) can result either from buckling of any part the stem (stem lodging) or failure root–soil anchorage system (root lodging). A framework for calculating risk lodging is developed which takes account shoot's height, ear area, natural frequency, weight, flexural rigidity and changes strength along its length. The model predicted that cultivars would occur half way up stem, wheat close to soil surface. These predictions are consistent with general...
This paper outlines the results of a physical simulation (at 1:700 -1:1000 geometric scale) thunderstorm downburst.Three different methods are examined in order to generate time dependent nature downburst: directly controlling fans and via two types opening apertures.Similarities shown exist between each method, although obtained from one approach favoured since they appear be independent downdraft velocity.Significant run-to-run variations experiment discovered general it is found...
