Abstract

This review discusses and compares different measurement techniques for liquid foam flow experiments. Particular emphasis is put on measurements of foam velocity and liquid fraction. Because foam is opaque, complex and fragile, many of the established tools of fluid mechanics are not directly applicable. Consequently, these techniques had to be adapted or new approaches had to be developed. This review elucidates the most common techniques and approaches based on optical imaging, electrical conductivity, X-ray and neutron imaging, ultrasound, magnetic resonance imaging, positron emission tomography, and small-angle neutron scattering. Each technique has its specific advantages and limitations, and needs to be chosen wisely depending on the measurement requirements. To that end, this review provides some guidelines to choose the most appropriate technique for a specific measurement.

期刊介绍： "Advances in Colloid and Interface Science" is an international journal that focuses on experimental and theoretical developments in interfacial and colloidal phenomena. The journal covers a wide range of disciplines including biology, chemistry, physics, and technology. The journal accepts review articles on any topic within the scope of colloid and interface science. These articles should provide an in-depth analysis of the subject matter, offering a critical review of the current state of the field. The author's informed opinion on the topic should also be included. The manuscript should compare and contrast ideas found in the reviewed literature and address the limitations of these ideas. Typically, the articles published in this journal are written by recognized experts in the field.
