Two-phase flow patterns and pressure drop inside horizontal tubes containing twisted-tape inserts
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This paper presents an experimental study on two-phase flow patterns and pressure drop of R134a inside a 15.9 mm ID tube containing twisted-tape inserts. Experimental results were obtained in a horizontal test section for ...
Colubility of argon and nitrogen in aqueous solutions of dodecyltrimethylammonium bromide (dtab) from 283.15 to 298.15 k and 101325 pa partial pressure of gas
The solubility of nitrogen and argon in aqueous solutions of dodecyltrimethylammonium
bromide (DTAB) were measured, using the drop pressure method, at temperatures
between (283.15 and 298.15) K and partial pressure of ...
Friction losses in valves and fittings for viscoplastic fluids
(Canadian Soc Chemical Engineering, 2005-04-01)
Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous suspensions of sucrose and bentonite. The rheological properties of these suspensions were ...

Correlated-informed neural networks: A new machine learning framework to predict pressure drop in micro-channels
(2022-05)
Accurate pressure drop estimation in forced boiling phenomena is important during the thermal analysis and the geometric design of cryogenic heat exchangers. However, current methods to predict the pressure drop have one ...
Design and construction of an equipment for the determination of solubility of gases in liquids
This paper presents the design and construction of a new isochoric saturation apparatus
for the determination of gas solubility in liquids based on the gas drop pressure method.
The major improvement of this design is ...
New prediction methods for CO2 evaporation inside tubes: Part I - A two-phase flow pattern map and a flow pattern based phenomenological model for two-phase flow frictional pressure drops
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
An updated flow pattern map was developed for CO2 on the basis of the previous Cheng-Ribatski-Wojtan-Thome CO2 flow pattern map [1,2] to extend the flow pattern map to a wider range of conditions. A new annular flow to ...
Coeficientes de perda de carga em valvulas e acessorios no escoamento laminar de fluidos nao-Newtonianos
(2000-01-01)
Friction loss coefficients for laminar flow of xantan gum solutions (concentrations in the range of 0.1-0.5% by weight) through valves and fittings were experimentally determined. The rheological behavior, studied by means ...
