Abstract






The present study offers the flow patterns and associated
structure of protein foam flowing in a horizontal channel. An
experimental equipment was developed to study the protein foam flow
regime and the related bubble size distribution. The foam formation was
performed with the help of a foam generator and transported in a
horizontal channel. The optical measurements were performed by a high
speed camera which enabled the foam flow visualization at the channel
wall. The foam flow pattern and the corresponding bubble size
distribution were studied as a function of the foam quality. As a
consequence of the higher drainage and gravitational effect at higher
gas flowrates, the foam structure resulted in different flow patterns.
The bubble size distribution was studied as a function of the volumetric
gas and liquid flowrate. The foam consisting of bubbles on the
millimeter scale showed a close fit to the log‐normal distribution.







Practical applications



One of the most important attributes of the two‐phase
flow is the bubble structure resulting in different foam flow regimes.
Since the final appearance of foam food products and their textural
properties such as their smoothness are associated with the foam uniform
distribution of the bubbles, the main objective of the present work is
given to provide the first experimental results of the milk protein foam
flow regime and corresponding bubble sizes during mechanical transport
through a horizontal duct.
