... transfer and fluid flow studies in single minichannels. This paper presents new experimental frictional pressure gradient data, relative to single-phase flow and adiabatic two-phase flow of R134a and R32 inside a single horizontal minitube, with a 0.96 mm inner diameter and with not-negligible surface...

...Chidambaram Narayanan; Djamel Lakehal Detailed numerical simulations have been performed to study the effect of flow orientation with respect to gravity on two-phase flow heat transfer (without phase change) in small diameter pipes. The Nusselt number distribution shows that the bubbly, slug...

... boiling by including additional forces due to fluid flow. The surface tension force per unit length is given by 1 F S ′ = σ cos θ Forces acting on a liquid-vapor interface In a nucleating bubble, the difference in the density of the two phases causes the vapor phase to leave...
