The Armfield C15 is a new computer-controlled subsonic benchtop wind tunnel designed for undergraduate teaching. A small, benchtop wind tunnel, with visible working section. A wide range of accessories and instrumentation options are available, allowing a comprehensive study of subsonic aerodynamics. The facility is suitable for undergraduate training and project work.

The Armfield Hydraulics Bench (F1-10) and accessories have long been the benchmark used in fluid mechanics teaching laboratories. The comprehensive range of equipment can covers all aspects of the teaching of hydraulics in a safe, visual and easy-to-understand way, backed up by first-class teaching materials. This range of equipment has now been extended and reinforced with an integrated range of hydrostatics teaching accessories together with some new hydraulics products. Thus the complete curriculum can be covered with this attractive range of products. The F1-10 is designed as a portable and self-contained service module for the entire range of F1 accessories and a few other accessories as well such as C6MKII and S16. Each accessory is supplied as a complete piece of equipment, needing no additional service items other than the Hydraulics Bench. When coupled to the bench they are immediately ready for use.

With the introduction of CAPTURE, machines that were once costly, cumbersome and difficult to use became affordable, space-saving and easy to use. Now CAPTURE MKII takes the concept forward into new realms of student understanding, adding superb visibility of the working of the bmachines and taking full advantage of the latest software and instrumentation techniques. All the CAPTURE units use standard PCs to display, record and manipulate the data. All Armfield CAPTURE units are now supplied with Armfield Armsoft LabVIEW™ based software to present and record the data in a way that is straightforward to use and understand for the student, yet offers a wide range of advanced features and capabilities. A common software format is used accross all machines. Similarly the machines all use a common interface unit, thus providing a cost-effective solution for laboratories requiring several machines.

The NA4 Ships Vibrations Test Model is designed to enable students to investigate a simple model hull form for resonance phenomena. It may be used in conjunction with the optional Armfield Flotation Tank or any suitable customer supplied tank. Many of the principal phenomena associated with ship resonant vibration are clearly demonstrated. At a more advanced level the distribution of mass and second moment of area may be calculated and using a Young’s Modulus value for the material of the ship shaped beam, the natural frequencies may be estimated by a simple tabular method or other means and compared with the measured value.

Attension® offers leading contact angle and surface tension solutions for industrial quality control and R&D as well as for academic research. The core of Attension solutions is a combination of easy-to-use, smart instrumentation with broad surface science capabilities.

Measurements

• Static contact angle
• Dynamic contact angle
• Roll-off angle
• Surface free energy (SFE)
• Surface tension
• Interfacial tension
• Batch contact angle
• Roughness corrected contact angle
• Interfacial rheology (viscoelasticity)

Technology

An optical tensiometer records drop images and analyzes the drop shape automatically. The drop shape is a function of the surface tension of the liquid, gravity and the density. On a solid, the drop shape and the contact angle also depends on the properties of the solid (e.g. surface free energy, topography). The captured image is analyzed with a drop profile fitting method in order to determine contact angle and surface tension. Surface free energy can be calculated by performing contact angle measurements with several known liquids.

As an optical method, the measurement precision of optical tensiometers depends on the quality of the pictures and the analysis software. Attension Optical Tensiometers utilize a high quality monochromatic cold LED light source to minimize undesirable sample evaporation. Image quality is guaranteed by a high-resolution digital camera, quality optics and the accuracy of the drop fitting method.
