Tilting influences the flow patterns and thus the heat transfer and pressure drop during
condensation in smooth tubes. However, few studies are available on diabatic two-phase …

Because of the importance of multiphase flows in a wide variety of industries, including
power, petroleum, and numerous processing industries, an understanding of the behavior …

Flows of two immiscible liquids are encountered in a diverse range of processes and
equipments. In particular in the petroleum industry, where mixtures of oil and water are …

The theory-based closure relations for the wall and interfacial shear stresses obtained
previously for laminar stratified flow, are extended to be applicable also to turbulent flows in …

Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids
in horizontal and inclined channels are presented. An iterative algorithm is proposed to …

Segregated and slug flows are two of the most common flow patterns encountered in two-
phase upward inclined pipe flow. However, the transition between them is ambiguous …

Experimental data are reported for condensation of R134a in an 8.38 mm inner diameter
smooth tube in inclined orientations with a mass flux of 200kg/m2s. Under these conditions …

New closure relations for the wall and interfacial shear stresses are suggested for the two-
fluid model for stratified laminar pipe flows. The new closure relations are formulated in …

Exact solutions for laminar stratified flows in inclined pipes are presented. These include all
possible configurations of stratified flows with concave and convex interfaces. The exact …

The effects of inclination on the characteristics of laminar countercurrent liquid–liquid flow
are investigated both experimentally and theoretically. Experimental results show that with a …
