Air-water two-phase flow and heat transfer in a plate heat exchanger
(2002)A plate heat exchanger is tested under two-phase flow conditions by using an air/water mixture as the cold stream. Visual observations recorded by a high-speed video camera lead to the construction of a flow regime map. ... -
Experimental evidence for a short-wave global mode in film flow along periodic corrugations
(2013)The primary instability of liquid film flow along periodically corrugated substrates is studied experimentally. Two different wall shapes, of the same wavelength and height, are tested for a wide range of inclinations. It ... -
Nominally two-dimensional waves in inclined film flow in channels of finite width
(2010)Traveling waves in inclined film flow in channels of finite width are never truly two-dimensional (2D) because of a long-range effect of sidewalls The present study documents the characteristics of the first waves that are ... -
Nonlinear dynamics of inclined films under low-frequency forcing
(2004)The evolution of an inclined liquid film, subjected to regular inlet disturbances of small frequency, f, is studied experimentally and computationally. The fluorescence imaging method is used to quantitatively document ... -
Numerical investigation of momentum exchange between particles and coherent structures in low Re turbulent channel flow
(2011)The interaction between particles and coherent structures is studied by using discrete particle simulation combined with direct numerical simulation of gaseous flow in a vertical channel. A conditional sampling scheme is ... -
On the stick-slip flow from slit and cylindrical dies of a Phan-Thien and Tanner fluid model. II. Linear stability analysis
(2013)During extrusion of viscoelastic fluids various flow instabilities may arise resulting in a distorted free surface. In order to investigate the factors generating these instabilities we performed a linear stability analysis ... -
Parameters Affecting Slip Length at the Nanoscale
(2013)We investigate liquid flows in various nanochannels and present the effect of all physical parameters affecting slip length at the boundary using molecular dynamics simulations. Our computational model shows that slip ...
