, using the recurrence features studied two-phase flow bifurcation due to turbulence, self-aggregation phenomenon, and stable flow conditions in a two-phase flow through a mini-channel using the laser transitivity data.
Stabilities of flows were also investigated by the largest Lyapunov exponent and correlation dimension. determining the borders between flow patterns. The flow patterns in a vertical minichannel were studied by Faszczewski et al. The nonlinear analysis of the flow of oil–water also carried out showing that such analysis is useful for identification of the flow patterns in inclined channel with larger diameters. Novel measurement techniques and nonlinear results analysis led to the identification of flow patterns of the oil-gas-water mixture from mini-conductance probe array and vertical multielectrode array conductance sensor. The correlation dimension and Kolmogorov entropy were used by Jin et al. , used selected nonlinear techniques including the Hurst and Lyapunov exponents, correlation dimension, and pseudo-phase-plane trajectory to analyse the pressure fluctuations of two-phase flow. To increase the ability to identification and interpretation, Wang et al. Such analyses have been carried out recently by many scientists. The alternative way of flow pattern identification is based on the analysis of dynamics of two-phase flow. In addition, the visual observations of gas and liquid arrangement inside the minichannel are used for flow pattern identifications. Usually, the two-phase flow patterns are identified by calculation of the average values of such parameters as mass or volume flux of phases, void fraction, phase momentum flux, dimensionless flow rate, superficial velocity, and others. Such applications demand understanding and identification of flow dynamics and two-phase structures.
Physiotools momentum android#
PT Momentum is available for iOS and Android and can be downloaded free of charge from Google Play or the App Store.Gas-liquid two-phase flows play important role in production processes such as petroleum industry, chemical engineering, nuclear and thermal engineering, and proposed innovative techniques of thermal energy harvesting in two-phase oscillating structures of heat pipes. This gives the therpist a great opportunity to review a client’s training program and assess their progress. They can set daily reminders, check their recent and upcoming exercises, receive automatic alerts about updated exercise programs and monitor their progress.Ī therapist creates an individual exercise program in PhysioTools Online, sends it to their client’s PT Momentum App, and monitors the resulting momentum value. The program comes with clear instructions, images and videos that ensure exercises are performed correctly. The rapid growth rate in PT Momentum users has been a very pleasant surprise, on the other hand I believe that, as clients now regularly use digital services, they also expect their practitioner to do so.” Mika Huotari, CEO of PhysioTools adds.Ĭlients can see their daily exercises at a glance on any mobile device. “It usually takes some time for changes to be adopted in our traditional therapy markets. Currently the app is available in a number of countries in Northern and Central Europe, however, now we are launching PT Momentum worldwide, using PhysioTools’ comprehensive international sales channels.,” Henrik Jürgens continues. “We have gained thousands of users in a very short period of time. We firmly believe that digital services are here to stay.” We see a clear demand for the use of modern technology by therapists.
Says Henrik Jürgens, CEO of GoodLife Technology, “The service has been very well received. The app works in connection with PhysioTools Online. On 1st March 2016, PhysioTools and GoodLife Technology are launching a new PT Momentum app worldwide. The service has been well received, showing that therapists are also currently undergoing a change towards digitalization. PhysioTools and GoodLife Technology have developed a service through which clients can receive their personalized exercise programs on their mobile devices.
