Armfield’s laboratory flow channel is one of the most important tools available to the hydraulics or civil engineer whether engaged in teaching basic principles or researching solutions to practical problems.
A comprehensive range of accessories are available for selection, these provide the basis for a large number of practical experiments in open channel flow.

Armfield Ltd are feeling nostalgic today…..
Take a look at these historical adverts from 120 years ago, the company had several foundry’s producing farm machinery, public works projects such as lamp posts but specialised in water irrigation. In 1898 Armfield started selling the Empire Turbine, a reliable, easy to maintain and operate motor for obtaining power from water, Armfield’s tag line was “Expert Engineers sent anywhere to advise upon ANYTHING to do with WATER”.
By 1938 Armfield had iron work, farm machinery, pumps, hydroelectric generators, water wheels and irrigation gates all over the world.
Current studies in geoscience and earth science include so much more than rocks and volcanoes. It looks at the processes that shape the earth’s surface, natural resources and how water and ecosystems are interconnected. It also looks at the effects these have caused in the past, present and what changes may need to be implemented for the future.
Armfield offers products for both laboratory and field-learning opportunities. It also introduces such diverse topics as crop water requirements, erosion, soil moisture content, ground water flow, plant water need and sprinkler irrigation systems.

The Armfield C6-MKII-10 Fluid Friction Measurements unit provides facilities for the detailed study of fluid friction head losses, which occur when an incompressible fluid flows through pipes, fittings and flow metering devices.
A wide range of measurements, demonstrations and training exercises are possible with the equipment:
· Confirming the relationship between head loss due to fluid friction and velocity for flow of water
· Determining the head loss associated with flow through a variety of standard pipe fittings
· Determining the relationship between pipe friction coefficients and Reynolds’ number for flow through a pipe with roughened bore
· Demonstrating the application of differential head devices in the measurement of flow rate and velocity
· Providing practical training of pressure measurement techniques
· Enhancing understanding of the hydraulic principles involved through the use of complementary computer software

Armfield’s range of computer-controlled products, provide not only real time monitoring and datalogging, but additional computer control of multiple variables used when undertaking experimentation.
For example, in our heat exchanger range both the hot and cold-water flow rates can be controlled from the mimic diagram screen in the HT30XC software, which is supplied as standard.
We additionally supply the ability for the pump speed to be controlled via a PID algorithm to achieve a stable flow of hot water through the heat exchanger on test. Changes to the flow that would be caused by effects, such as viscosity reduction due to increasing temperature, are eliminated by automatically adjusting the pump speed.

Water engineering research continues to be paramount in areas such as coastal research, environmental modelling, sediment transportation and irrigation studies. For over 50 years, Armfield have designed and supplied major research and teaching flumes worldwide.
The education teaching flumes allowing fluvial mechanics experiments to be carried out in related topics such as river flow and sediment transport, initiation and characteristics of bed-load motion,
general and local scour in open channel flow.
Bespoke open channels to suit specific design criteria can be produced by the Armfield engineering team. Our team utilise their extensive knowledge to deliver a product designed to give the best possible performance over a wide range of applications with user friendly control and instrumentation.
Armfield’s responsibility covers design, materials and parts, fabrication, delivery to site, final layout of the work on the site,installation and finishing of the flume to a complete operating condition, all overseen by our dedicated professional services team.
Armfield’s American office had their Industrial Food Department out showing at the South-eastern IFT Hybrid Food Expo and Orlando at the IFT Local Suppliers Shows.
Titus Porter was on hand to explain the vast range of products available from Armfield related to Food Technology. As usual, the shows were very successful even during these difficult times.

The Armfield F1 Fluid Mechanics products provide a comprehensive range of hydraulic models each of which is designed to demonstrate a particular aspect of hydraulic theory.
The Impact of Jet Apparatus, F1-16. This consists of clear acrylic test cylinder, into which water is fed vertically through a nozzle. The water strikes a target mounted on a stem. A weight pan mounted at the top of the stem allows the force of the water to be counterbalanced by applied masses.
Experimental outcomes include:
* Principle of linear momentum
* To investigate the reaction forces produced by the change in momentum of a fluid flow
* Measurement of the forces produced by a jet impinging on solid surfaces which produce different degrees of flow deflection
Fluid mechanics has developed as an analytical discipline from the application of the classical laws of statics, dynamics and thermodynamics, to situations in which fluids can be treated as continuous media.
The particular laws involved are those of the conservation of mass, energy and momentum and, in each application, these laws may be simplified in an attempt to describe quantitatively the behavior of the fluid.
Water engineering research continues to be paramount in areas such as coastal research, environmental modelling, sediment transportation and irrigation studies. For over 50 years, Armfield have been designing and supplying open channel facilities (also referred to as flumes) to hydraulic laboratories throughout the world.
Our brochure presents the standard range of channels/flumes available from Armfield for teaching and research purposes. Bespoke sizes and layouts to suit specific design criteria can be produced and the Armfield engineering team work closely with our customers to make sure the brief, deadline and installation designs are fully met.
All our flumes are supplied under the guidance of the Armfield professional service team who will oversee the transportation, installation, commissioning and training on site.
The Armfield Multi-Pump Test rig can accommodate both rotodynamic and positive displacement pumps, and is supplied with the most common example of each type as standard (ie a centrifugal pump and a gear pump).
A range of other pump types are available as accessories, (including axial, turbine, flexible impeller, diaphragm and plunger, plus a second centrifugal pump for series/parallel demonstrations). Up to four pumps can be accommodated simultaneously within the rig for use within a single laboratory period, and each can be run without disconnecting any pipework or connections. Further pumps can also be easily interchanged.
