Oil–Water Flow Pattern Transition Prediction in Horizontal …

Flow pattern transition prediction models are presented for oil–water flow in horizontal pipes. The transition between stratified and nonstratified flow is predicted using Kelvin–Helmholtz (KH) stability analysis for long waves. New, simplified, and more practical physical mechanisms/mechanistic models are proposed for the prediction of the …

Modelling flow pattern transitions for steady upward …

Models for predicting flow pattern transitions during steady gas-liquid flow in vertical tubes are developed, based on physical mechanisms suggested for each transition. These models incorporate the effect of fluid properties and pipe size and thus are largely free of the limitations of empirically based transition maps or correlations.

Horizontal Pyramid Matching for Person Re-identification

Despite the remarkable recent progress, person re-identification (Re-ID) approaches are still suffering from the failure cases where the discriminative body parts are missing. To mitigate such cases, we propose a simple yet effective Horizontal Pyramid Matching (HPM) approach to fully exploit various partial information of a given person, so …

Flow pattern based two-phase frictional pressure drop model …

The present work completes the fourth basic step in LTCM's flow pattern based work on obtaining a unified approach to modelling two-phase flow and heat transfer inside horizontal round tubes: (i) a generalized flow pattern map, (ii) a flow boiling heat transfer model, (iii) a convective condensation model and (iv) a two-phase frictional ...

Flow Boiling in Horizontal Tubes: Part 3—Development of a …

A new heat transfer model for intube flow boiling in horizontal plain tubes is proposed that incorporates the effects of local two-phase flow patterns, flow stratification, and partial dryout in annular flow. Significantly, the local peak in the heat transfer coefficient versus vapor quality can now be determined from the prediction of the location of onset …

UPDH and/or LPDH showed a significantly positive correlation with SN-MP, S-Go, Ar-Go, N-Me, and ANS-Me. Understanding the relationship between dentoalveolar height and vertical patterns can help orthodontists modify the position of the teeth to correct the skeletal discrepancy in vertical relation, thus preventing excessive …

Effect of pipe diameter on flow patterns for air-water flow in

New results are presented on interfacial patterns observed for air and water flowing in horizontal 2.54 and 9.53 cm pipelines close to atmospheric conditions. This work differs from previous studies in that measurements of pressure fluctuations at two locations separated in the streamwise direction are used to detect slugs. The liquid flow ...

A flow pattern map for gas—liquid flow in horizontal pipes

Abstract. Various flow pattern maps for two-phase gas—liquid flow in horizontal pipes are tested against the 5935 flow pattern observations presently contained in the UC Multiphase Pipe Flow Data Bank. A new flow regime correlation representing an extension of the work done by Govier and Aziz [3] is presented and is shown to be in …

Flow pattern based two-phase frictional pressure drop …

Many flow pattern maps are available for predicting adiabatic two-phase flow regimes in horizontal tubes, such as Baker, 1954, Taitel and Dukler, 1976, Hashizume, 1983, Steiner, 1993. Most of them were developed for adiabatic conditions and then extrapolated to diabatic flow, so the extrapolation procedure may not always produce …
